I'm looking for a way to get the turbo to spool quicker. I was riding with my cousin in his 06 max tonight and his turbo spools so much quicker. Our trucks are about equally as fast, but his power is more instant. We have identical mods. Obviously his VVT is working better than mine! Will the boost stick do what I'm wanting and make it act more like his?

Put an EGR blocker plate in and a boost stick, that'll speed her up a bunch.

Boost stick and straight pipe made it almost instant.

OK I just ordered the boost stick with extension. Supposed to be easier to install and uninstall I guess? Anyhow, it is on the way. I'm about ready to order the EGR plate, but was thinking I didn't need the fingerstick as mine is an 05. The 05's weren't throwing a SEL without the fingerstick last I remember.....right?

Are you tunning the low boost on 5?

Yep, with FE9 emissions you shouldn't need the finger stick. Just put the plate in and unplug the EGR valve when the engine is cold.

I can turn the low boost fueling to whatever level I want and it will never spool as quick as a LBZ

Cool. Thanks for the confirmation!

It's all ordered now.... all this is getting me... SPOOLED UP! HAHA Thanks!

IIRC the vane structure on an LBZ is different than on an 2nd gen LLY. I could be wrong.

No, I don't know for sure either, but I could easily agree with you. His turbo reacts so much quicker, it not even funny. I've been plotting how I am going to swap him turbos some night when he's fast asleep!:D

Tryed the boost stick with stock tune on my LLY, definately worth it. Much improved response. Didn't try it with my Predator after being advised by Kennedy that the two might not work that well together. Sold the stick to a friend with an LLY running an early Qaudzilla that didn't make boost, these two together work great, better response, cleans up the smoke. Just remove your ac pump to get at the plug.

If you have the older predator version the BS will work fine since that version of the predator didn't change the stock boost tables. I beleive it was V2.00 or V2.01. V2.02 is the latest.

The predator and boost stick should be ok on the 65 Hp lvl, but on the 85 or 100, you would definately have to remove. With the BS and Predator on 65, the only time you can get into trouble is in 4th and 5th, the boost can climb to 35 PSI.

Not sure what everyones thoughts are, but I think if you occasionaly go that high but keep it under 32 most of the time, you SHOULD be ok...

Do you still have your LB7? I don't think those have VVT's?

If you have a lb7 you can get the PPE boost valve

which he has...

BS are only for VVT's.

Correct

Just for clarification, does the egr blocker increase your boost pressure? Or just keep the EGR from blowing open when the boost pressure is increased?

FWIW LBZ turbos will run on LLY... gasuout is and he noticed a big diff between stock lly and lbz turbos:D

McRatt ran one also but it didn't last as long as the LLY one.

Version 2.0 is the one you're referring to; according to the literature I've read, version 2.02 doesn't require the BS as it will do everything that the BS does.

As you can see in my sig, I have version 2.0. Since I don't have the original receipt for my Predator (bought it on eBay), it'll cost me $100 to get upgraded to 2.02 (if I had the receipt, upgrade would be free). Rather than buy a BS, I plan to upgrade my Predator - makes "removing" the "BS" a simple step of returning to stock, which ya gotta do to go to the stealer anyway. :rolleyes:

well s how long it take johny to blow his up :rolleyes:

which he has...
yeah i have it but i dont think it did muck if any difference. i dont know my torque converter is going out i just feel like ther is a bigg part of the power its capible of thats not there , still im outrunning lightnings and cobra's but just feels like she isnt getting all the power/ :confused::think:

the diomand eye down pipe i reckon helps alot too

They will interchange. I ran a LBZ turbo on my o5 LLY. I noticed a HUGE difference in the spool up, and low end. Watch the EGT's with the big tunes though. They will run alittle higher.

I think that's what McRatt found out the hard way.

Thinking a little about that I wonder if the fact that the exhaust housing being smaller if it causes an increase in exhaust back pressure which causes the turbo to spool faster but also builds the EGT's faster. I guess what is more efficient for the turbo isn't always more efficient for the engine since we want to get the exhaust out of the cylinders as fast as possible to eliminate heat and drag on the motor. Of course it's early and I just got out of the gym so I could be blowing chunks in this thread right now.

I would like to get this straight as I have been thinking on installing a blocker plate as well.....on my 05 LLY, running a predator 2.00 can I install a plate and unplug my EGR and NOT need a boost stick or have any problems or issues?

I installed my EGR blocker plate yesterday and unplugged the valve and no problems or codes. I did have a initial problem because I unplugged the wrong wire. Ran a scan and cleared that code. Works fine.

If you have fed emissions then you will be fine with just the blocker plate. If you have CA emissions you'll need a Finger Stick to eliminate the EGR codes. The Boost Stick is just to increase the boost not eliminate EGR codes.

Wierd thing is my 07 LBZ has 200-300 deg lower EGT's than my 05 LLY had with even the LLY turbo. I think the higher rail PSI of the LBZ is alot more efficient. If you could build a LLY tune like the LBZ with 26,000PSI. I think the EGT's would be low. You would Probably need a LBZ CP3 as well. I was going to try that on my 05 LLY, I even had the LBZ cp3. But I sold everything when I got my 07 LBZ.

so the lbz tkurbo will bolt right up to my lly but what about the boost tubes i know the lly runs 2.5inch but dousent the lbz run 3 inch? i might be wrong here wouldnt be the first time

Maybe the fact also that it spools up faster helps keep the EGT's down from the git-go. I run higher than 23Kpsi out of my stock LLY CP3. I think the injectors are a different design on the LBZ as well so this also may aid in the fuel burn.

Got the boost stick and EGR blocker plate on. I'd give the BS a :thumb:

If you have a blocker plate, then you REALLY don't need to unplug the EGR valve. Let it work normally. It's not like you are gonna get any flow thru it and this way you won't have to worry about it seizing up or somthing stupid like that.

clone,
so how was the boost after the bs? noticeable ?

If you have fed emissions then you will be fine with just the blocker plate. If you have CA emissions you'll need a Finger Stick to eliminate the EGR codes. The Boost Stick is just to increase the boost not eliminate EGR codes.

So is the finger stick not being needed for federal trucks true for ALL model year LLY's? I know i have an LB7, i'm simply asking for personal knowledge.

Absolutely. It is still not AS responsive as an LBZ turbo, but much closer. The BS cleaned up my exhaust when on higher power levels SO I know I'm using that fuel now! I don't know the ACTUAL additional boost I'm getting as the edge boost reading is getting tricked by the BS.
