Has anybody tried the programmer or even heard of it .
Claims to add 114 horses to an 06 lly

I wouldn't let that clown tune my bicycle.

Given that the 06 has a completely different confuser and no doubt new system software I don't think this dude had time yet to get a decent tune together. I'll go with Max Power.

jdwelcher,

When all you do is run up fuel pressure it probably will work, but I am with MAX Power on using it.

Makr @ DPPI

Doesnt the 2006 LLY have fuel rail pressure thats already cranked up a lot from the 2001-2005 Duramax's? Or is the increase in rail PSI only happening with the LBZ's?

I wouldnt trust it. Dr Performance isnt known to be a great brand anyways.

That's odd as I know a guy that put his injectors on his stroke and picked up 100 hp and 2 mpg. All I see is bad press with no examples here. Don't take that as I think you guys are wrong but as wtf happened to make you say these things?

For starters his harness box is a pressure box which is bad, bad, bad. A terribly overpriced pressure box at that.

Pressure box? As in more fuel or boost? If you read his site he pretty much rails against increasing fuel so that would seem abit hypocritical of him. Has anyone tried his injectors on the LLY?

As in increasing fuel rail pressure.

You know what, rather then arguing here why don't you go buy one and tell us all how it is? ;)

:muahaha: ;) .

Hehe... settle down Max... No-one is arguing with you, but just looking for information and discussion. If you don't want to give it just ignore the post. :)

Edit: I understand Max that I should look at 7200 posts on a forum and just assume that the poster knows it all. Then again the best you can reply to this thread is "I wouldn't let that clown tune my bicycle" and "why don't you go buy one and let us know". How about you just come on in and calmly explain to the little people the details behind your thoughts. With 7200 posts behind you I am sure you have the time. If that's too difficult then maybe just link us to the threads we may have missed. After all, isn't that what this forum is about? :end Edit

My point is he rails against overfueling on his site. I will take a guess that he see's higher pressure as better atomization and not overfueling. Since Max will now be ignoring my posts does anyone want to chime in? ;)

My question was has anyone tried his injectors on an LLY? At 2k that's abit to expensive for me to experiment on and the only box I am interested in at the moment is something that will correct for my tires since my dealer can't seem to find a way. Unfortunatly the only thing I have seen so far for that is the Hypertech. I am talking about correcting the stock program and not having to watch a separate box for it.

Electrically, existing plug-in tuners like the Edge will not work. The pinouts on the engine connector are different on the '06.

Anyone who says they are running an existing, unmodified Edge on an '06 LLY or LBZ is lying.

Remember, '06 replaced the Delphi box and the fuel control box with a single Bosch controller.

I went back to the Dr.'s site and I don't see where they claim 114 hp for the LLY out of a tuner box. Where did the OP get his info? The only box for GM that I saw was up to 03 and the numbers for that are 80/175. I did see 100/220 from his injectors though.

I honestly have no first hand experience with the product and I shouldn't comment any further.

However, since you asked me to clarify:

Over fueling has nothing to do with raising fuel rail pressure. Our fuel systems run in excess of ~23,000 psi (excuse me I don't remember the exact number). So let's say for argument sake say that Dr Performance's predator raises fuel pressure to 30,000psi. You are now running almost 50% more fuel pressure to a system that is designed to run under 25,000psi. See a problem here? As for accuracy of his claims, he CLAIMS that his performance module actually INCREASES engine life. Give me a break. You are going to increase engine life by increase the RWHP almost 50% by increaseing fuel rail pressure and on top of that you are going to INCREASE engine life? LOL

Did you notice how just about the only place you can find his product is on ebay? Don't you think that if his product was so great that at least even one of this sites advertisers would sell his product?

So while I have no actual first hand experience, I do know that I will stick with the tried tested and true products on MY duramax. Edge, TTS, PPE, Diable Sport Predator, Van Aaken come to mind. You are free to do what ever you want, let us know how you make out.

p.s. I don't know it all. I never have claimed to know it all. I help out where I can and thats about it. If you don't like my opinions that is your choice.

:) My only opinion of your opinion was that it had nothing backing it up.

Now that you have added to it I think we all have a better understanding of your point (or should I say opinion). I thank you for making the effort to do so.

It wasn't until I bought my truck that I even went to the Dr. Performance site and I was quite surprised to find a tuning box for sale on it. If anyone has missed what I know of Dr. Performance I will throw it down again here. I have a friend that is the instructor that put together the apprentice program for Cal-Trans. This guy has forgotten more than I may ever know in fliud power and mechanics. He taught me how the HEUI injector works among many other things. He was given a set of the Dr.'s injectors for his 7.3 Stroke. He dyno'd it before and after and told us he got 100 hp and 2 mpg improvement from the change. He is the one who told me about overfueling being not necessarily a good thing and the view of it from Dr. Performance in their talks. So, in the end I only know one guy that runs Dr. Performance product and he is very happy with it. I doubt the fact he got them for free jades his opinion but the arguement could be made from someone who doesn't know him. I would love to hear from anyone that runs his stuff on an LLY so I don't have to be the guinne pig.

I honestly haven't looked to where I can buy his product because I am not ready for it yet. I also have no idea why the vendors here don't sell his product. There could be a very good reason for that, but then again it could be your right in that he makes junk. Time will tell.

We don't have to agree Max, but I bet we will on alot of things. I just expected a better explanation or point of view from an established member like yourself. I apologize if I came on too strong about it. Thanks again. ;)

Huh!! you sound like the spokesman for Dr. Performance.:eek:

NO really though you yourself even noticed that none of the vendors here carry his product.....there is a reason for that. Your money can be better spent on other products like EDGE. You bring up the fact that a few people have had problems with their EDGE Box, well thats okay because EDGE has outstanding customer service and has already fixed their problem.

Whatever... I have no idea who your talking to but all I see in this thread is fluff. I know there is a reason the vendors don't carry his product. What I don't know is WHAT THAT REASON IS? Is it because they can't get him to give them a price break so they can make money? Is it because his products are bad? Anyone can type in that someone sucks... yippee skippee. Now why don't you link to the threads that prove it or just prove it yourself. I am not interested in your feelings, I would like to see some facts. I myself am not a Dr. Performance groupy, and I refuse to let you calling me one let you off the hook of providing facts to back up your claims. If all you can do is throw derogatory coments out then why even bother posting at all? Your useless to those of us that would like some real information, good or bad. The only facts I have at this time is a friend who has used them and is satisfied with them.

I know Max is looking for info and I thank him for giving his time to us. That is what I believe this forum is about.

The original question was "Has anybody tried the programmer or even heard of it. Claims to add 114 horses to an 06 lly". If you check out the site, you will find the module plugs into the fuel rail pressure sensor and the harness to the ECM (watch the installation video for GM). In other discussions they talk about raising the rail pressure from ~23000 psi to ~26000 on the Cummins. Clearly they are raising rail pressure. I found no information regarding the injectors except for power increase claims.

I saw that on the Cummins but not until after I posted that. I will look to see what the fuel rail pressure relief is set at. I will also see if I can find whether it's adjustable or not. The Cummins article was saying that with the higher rail pressures the on time of the injectors was narrower so you could get an increase in economy with it. Honestly, for this day and age, their site leaves quite abit to be desired. I need to go watch the install video, I didn't think I would get much info out of it. My bad.

Edit: How does All Data manage to stay in business? Nothing on there that helps at all. I don't think they show a difference between the LB7 and LLY as it gives a time for replacing the wastegate. (I had 2005 selected) Sheesh...
