Has anyone been on the PPE site and checked out the new LLY Boost Controller? Anyone running it yet? Have not seen any threads on it and just wanted to know what was going on. They said it can be controlled from in the cab up to 40 psi on the LLY. Just curious to see if anyone has run it yet and what they think about it.

McRat might know a little about it...........

For running stacks and racing it's the hot ticket.

You can adjust your boost to any point you want from 21PSI to 40+ PSI, but you will find the best ET's at 32-34.

Is it worth the money with a Edge w/attitude.

probably not brich cuz i heard your tranny is junk :lol:

You would know it Hahaha!!!

I went to the PPE site. I didn't find it there. Is it on there yet?

Very first page.

I found it, thanks!

If your not gonna be that aggressive I would suggest a Fingers boost stick. Neat piece. Simple and effective.

Correct. The FBS will give you good boost for running normal tuners. I needed an adjustable, and at the last minute, PPE threw me a beta unit.

I did not know the PPE adjustable would come out before the Challenge, so I was going to race Steve Cole with the FBS instead. I would have destroyed him either way, but I didn't know that before the race.

Jonathan has given me alot of help with my LLY's and I feel bad. But I will always run the fastest combo I have available, and the FBS was too high for my stack.

:exactly: Unfortunatley "get-it-now-itis" is a dangerous thing!! HURRY FINGERS!!! :lol:

I'm home finally. I will be sending a batch Boost Sticks to JK for distribution later this week. Far from a perfect product, but it will make many people happy.

Fingers I need 2 more. Notice I did not say WANT. Do I need to contact JK.

I'll look to list the product and details and as soon as I get images I'll add them

A list might not be a bad idea . . . There's probably going to be a run on the first few batches. :D

That will all be up to JK. Production ramp up will take time, but all orders will get filled. I am in and out of town for the next 2 months, so any production problems linger till I get back to deal with them. Even so, I expect to ship 100 or so to JK by the end of the week.

price?

I recieved a PPE Boost controller last Saturday, it took about 10 minutes to install and have to say it works great. I run a PPE hot excelerator on max and Edge Box on 3 stacked and it clears up all my black smoke. Without the boost controller it is an extremely black cloud, anytime I would roll on the throttle, not any more. I just got another boost guage (Auto Meter) today, to install and check numbers because the read out on the edge is not that accurate. Definite power increase now that more fuel is being burned. It is adjustable with a small dial and has a switch to toggle into race mode. It doesn't set any codes either. It has factory style plugs and the box that houses the electic is water tight. Why wait when you can have a controller that is adjustable and works as PPE states on the site.

yes, the PPE boost controler sounds like a very nice gaget, but the price is abit steep for me right now, that is why i was wondering how much the "finger it out stick" will be

Again, JK's call. I didn't want to be involved in the distribution end this time. PITA. Single source, single price to one person makes my life simpler. Much simpler. Also frees me to worrk on other projects. It also benifits the people buying the BS. Since I am in and out of town so darn much any more, they get their orders filled in a more timely manner. JK already has the web space, the Credit Card order taking and, well everything I don't and don't want to get involved with.

Wholesale prices are also available for other distributers through JK. They can contact JK directly.

well i see that the PPE boost controller is 330 what is the stock cost

Bs <$100

cool

I'm calling JK asap!!

PPE boost controller is definitely fun. I have mine set at 32psi and still get smoke at WOT in 5th. At 3/4 throttle, I am seeing 26ish psi and no smoke pulling really strong. I am running this in conjunction with their Hot +2 competition tune. I need to dyno this setup soon and see what numbers I can get from it.

On a side note, the Fingers boost stick is a neat piece. I've had the pleasure of seeing one in person. I prefer the adjustability though with unpredictable stacks.

It looks like MaxPower is running a bs w/ his stack and getting the optimal 34psi of boost. Why spend the extra $200+ on the PPE if the bs gets you where you need to be?

I am only getting 34 psi in 5th gear. Is 1,2,3,4 gear I am seeing about 28-29 psi.

Great place to stop without excessive drive pressures.Good job guys.

It's really a matter of your goals. If you want to set your truck up once, and stop, the FBS is a great product. If you are constantly changing your setup, you will need adjustability.

I think I was one of the first people to hit 45PSI stacking. :D Nobody believed me at the time. ;)

I'd like to see it run around 32-34 all around. It sure cleans up the smoke in 5th with over 30psi and it flat out halls a$$ in 5th as well.

So would I benefit from the PPE boost controller if I'd like to cut my EGTs down while towing?

I'm afraid to look at my pyrometer...

I've seen it enter the red zone from the wrong end of the gauge.:eek:

Yes. You will also gain with the Fingers BS stick.

I know what you mean. 1800++++++ And people are worried about pushing 1300 degrees. ):h

Ouch! I can't believe you haven't burned up a turbo yet. Either way, keep up the good work! :ro)

I have been playing with the PPE boost controller for 2 days now. Install was simple. I think it is great. You can run along stock if you want and you can turn it up and drop egts while cruising. It took me some time today playing with it to get a feel for where the dial setting needed to be for the boost I wanted. Now it is easy to set it for 32-34 psi. I haven't really played with the switch yet.

I am looking forward to the dyno day this weekend in Portland. I am also anxious to try towing with the boost controller.

mwgasman, did you just call PPE to order the Boost Controller?
Does anyone know: is there any place on-line to buy the PPE Boost Controller????

--Ben

I got it direct from PPE the day it was released

I know what you mean. 1800++++++ And people are worried about pushing 1300 degrees. ):h

point i have made many times, and got blasted for... :confused:

(see sig)

Please put your LLY Boost Controller up for sale online. Some of us working stiffs can only access the internet, not a phone. Thanks!!:ro)

P.S. My credit card is burning a hole in my pocket......

Ive been playin with the race mode switch, and man does it really bring in the fuel quick! And still gives me my boost that I set with the dial.....

When I turn the race mode off seems to have less fuel from the initial take off, but much cleaner exhaust all the way through at all throttle pedal positions......cool......:ro)

cause sometime when the man (police) is behind me i do not want to leave smoke trails........):h

Markstr43:

Your right, that race switch does cause the fuel to be added sooner. It pulls harder right off the line with very little smoke. Before it smoked like a coal train.

Also I hooked up to a big trailer and pulled about 5 ton around town. Before the PPE boost controller the EGT was real high around 1400 - 1500, now it never topped 1100 with the PPE xccel hot on max and edge on 2 and the PPE Boost controller. I was turning the dial watching the Boost guage go up or down.

Is the fingers boost stick switchable or variable?

It's time to add more fuel.

Fingers Boost stick is not variable. I think he plans on selling a variable unit at a later date at a higher price.

Do any vendors carry the PPE boost controller, or do we have to go directly through PPE?

Fingers Boost stick is not variable. I think he plans on selling a variable unit at a later date at a higher price.

Adjustability has not been a part of the boost stick to keep it simple. I see a trend for people to run too much boost and push the turbo well beyond the efficient range with drive pis exceeding 80 psi :eek:

At our modest 28-ish psi boost levels, the drive psi is already at around 65 psi. In our testing we found that the pressure ratio quickly escalates when we exceed this area.

So how much drive pressure is too much?

Technically speaking, I think the Ex-brake mfrs shoot for 55-65 psi at Dmax's recommendation. BD or Banks could elaborate on this. Older Cummins required heavier valve springs to use an Ex brake...

What does a stock Duramax run for drive pressure at it's highest?

Good one for Fingers, but it looks like 33-ish on the dyno with stock tune.

So basically by turning it up to say 30+ psi we are seeing more drive pressure then we would see with an exhaust brake engaged. That is a pretty major restriction.

Any idea what a stock LB7 running similar boost would see?

Time for bigger turbos.

I'll bet Juice's turbos have seen as much drive pressure as any out there!

Let's get a gauge on that truck!

Stock boosts of about 22 PSI will give you drive pressures around 40 PSI at 2800 RPM regardless of tune. At 30 PSI boost you are running in the 60 PSI drive pressure range at 2800 RPM. To make 34, your drive pressures will start to go over 80 PSI, and if I read the data right, will start to strangle the engine badly. The sweet spot is just under 30 PSI. You can make more power at 32 PSI with enough fuel, but not efficiently. 34 will actually lose power above 2800.

It is not clear to me that the turbo is the limiting restriction. There are indications that it is a combination of the downpipe and exhaust manifolds. I hope to look into this some more when I get off the road. Turbo headers and monster down pipe anyone?

There is nothing wrong with PPE's approach. If there is a downfall, it is the lack of consistancy that comes from playing with the dial. Who could resist. Even with the BS, I have found myself playing with the thottle just to hear the turbo sing.

The next BS versions will actually be a set of fixed boost maps that can be selected with a push button. No dial. But that is a little way off and, you guessed it, these will cost more when they hit the market..

BTW, it is not my intention to highjack this thread.......

I have run the PPE at full boost, it pulls harder and with a lot less smoke. As for restricting the exhaust, I have yet to notice an exhaust brake effect what so ever do to running higher then normal boost. As for having a dial to adjust boost, this allows everyone to find there ideal setting, no two trucks will ever be the same. And the race switch is the icing on the cake, more fuel at lower rpm to get things rolling.

Don't play hate a good product that works.

Hey Steve, you're starting to come across as a PPE plant. Fingers is very knowledgeable about this stuff, and is helping us with an inexpensive mod.

Maybe put your truck in your sig. with mods so we can see what you run.

I think there is a market for both kinds of controllers.

The PPE Boost Controller is very trick, adjustable, and has a low RPM power setting. Yes it costs more, but trust me, if you are racing alot it's a great tool.

The Finger Boost Stick is for those who run a single tuner, and want more power with less smoke at a low price.

I've tested both products, and they are both good.

It won't 'feel' like an exhaust brake. No one ever said that. What is a fact is that it will run higher back pressure which is in excess of what you would see with an exhaust brake. You are also seeing that under heavy fueling unlike an exhaust brake which would only see it after your let off. If that back pressure wasn't so high you would see a lot more benefit from the higher boost. Also when the back pressure gets too high we run the risk of breaking things. Will it happen? Who knows. Hopefully you don't find out the hard way.

Fingers could easily run higher pressure with his boost sticks but he chooses not to because he is not willing to sacrifice your motor to make a few bucks. Sorry to put words in your mouth Fingers, hopefully everything I said is accurate.

Steve, if you are a plant tell your folks at PPE to put the controller up for sale online!!! :rant:

:eek:

Where did that come from?

If you are cranking the dial all the way, then you are proving why a dial can be a bad thing. There IS such a thing as too much boost. But heck, if your happy, bless you and enjoy the bliss.

You guys are to much, call off the dogs. If I was a plant why did I spend over $300 for a boost controller. I have no affliation with PPE what so ever.

Guys, I just visit this site for information, no more no less. In the past I've searched for topic such as the throwing codes with a new exhaust. And I found an answer with the Finger stick I purchased and it works great. PPE sells a similar product for more money, but I didn't buy there product.

I thought that the who idea of this forum was to pass information and help other people, not get questioned like I did.

So I want to increase the power of my 05 GMC CC short. As I stated before it has an edge box on 2 and a ppe hot programer on max and a couple of other small mods. I read the post regarding the fingers boost stick and even emailed fingers and kennedy to see when it would be available. I was told soon, fine I can wait. But then I see that ppe has the same product that is available now. So I call then, overnite it, and get it one day after it is released. Guess what, the product works as stated. So, trying to inform guys like me that can't wait, I post the success I've had with the ppe product and tell them how great it works. I'm just trying to make a return to the forum that gave me so much information in the past when I had my 02 lb7 and now this truck. I didn't railroad some else's post about another product talking how great the ppe controller is. I just stated the facts about how well the product works and answer a few people statement from the experiences I've had.

Why is it alright for beta testers to post how well other products work when they are not yet available. Sounds like building hipe to me. All the hipe about the fingers boost stick worked, but instead I just bought the ppe controller instead.

As for being a ppe plant, I'm not. You can call them just like I did and give them your credit card #, If you can't wait either.

I'm going to make a prediction about LLY failures.

If you use a programmer that raises the revlimiter or boost pressure or both, AND use a boost controlling device in excess of 32-35 psi you are in extreme danger of catastrofic(sp) engine damage.I have seen drive pressures well in excess of 100 psi @35psi.This exteme back pressure is very close to holding the valves open.This now coupled with 4500 rpm rev limit and marginal valve springs with this kind of back pressure is a recipe for disaster.

I have not tested the drive pressure @ 4500 rpm but I can venture a guess at 35psi boost to be in excess of 120.psi.You could probably make 50 more hp @ 30 psi.This turbo is not going to fail, the engine is going to.A valve hits a piston and game over.

The LB7 could actually make more boost pressure than drive pressure at times. The LLY NEVER makes more boost than drive pressure.Lets understand, a varriable nozel turbo is not for big hp,its for driveability and emissions.

Now with that said, My prediction is a sharp rise in engine failures with boost controllers used in excess of 30-32 psi. Call it a vision or intuition but I see the writing on the wall.This is a GREAT mod if you keep it UNDER 30 psi.I see 28-29 optimal.The adjustable PPE is great for different combo's but just understand what you are doing to get more boost and use your head. PPE can't test every combo or bastard stack so just beware.
:rant: Tim

Do any vendors carry the PPE boost controller, or do we have to go directly through PPE?Merchant Automotive has them...I got mine yesterday.:ro)

This guy i know, says his 04 powerstroke w/a bullydog chip will top out at 60 psi. And he does it all the time! So why can't the duramax do that???? I have hit 35 psi boost on my lb-7 w/the edge stacked w/the predator. Also reached 1,496 on my egt I have had no probs. Almost forgot. The 60 psi on his powerstroke is B.S. but he beleives it,but wont show me it.Huh makes since now ford people lie!

I touched off 40lbs. a few times while dialing in the PPE Boost molester...Max I wanna run is about 32lbs. 1496 degree EGT for a few seconds is no biggy, I can bury my EGT's past 1600 easily just on the street.
