As the title says. I cant add boost through my DSP. Basically what I've come to guess through some searching is that I have a tuen with a torque limiter active. I logged a few pids with the Data Viewer and found that my numbers were as follows at 5200 RPM in 3rd:


TOTAL TRQ DESIRED: 331.6 LB-FT
TURBO TRQ POTENTIAL ST: 378.4 LB-FT

Tune issue?

I do believe my Vac lines are correct and I dont appear to be leaking. The car holds 14 psi all day long but will not go any higher no matter what % I add. If this is the case, I need to bottle up my stock tune and my last tuen written (Adjusted 93 Perf) and send them out to you for a fix?. Also Whom should I send it to.

Much appreciated.

Bump for an answer...

post up last tune written please.

I just installed Meth last night so I'm running the stock Canned 93 tune. no adjustments. I'll load it up after work so you can tell me something about it. Thanks.

If you have any issues unziping, it may be due to them being zipped up with WinRAR. I compressed them as a ZIP file though, not a RAR file, so they should be usable.

here you go.

And a many thanks to you good sir!

O and lastly, Do I want to install my original tune back onto the car before loading this?

No...just load it over the current file.

Well, I loaded it up, pushed it to 20% additionl boost, and it didnt seem to do much, if anything at all...From your experience that should have braught it up a few pounds I would assume?. I may go ahead and do a boost leak test tomorrow...but I doubt I'm leaking. Hate to keep pestering you, but its frustrating not being able to hit an easy goal lol. 20lbs is all I'm looking to spike.

Also, I doubt their messed up but, would vac lines impact it that much?. i seem to be at like 16 psi. Super super rich, im only dding boost from the 3-4k and 4-5k range. Should I add way up top also or would you considder this a waste since its prolly going to eb falling off by then?.

vacuum lines are more important to proper boost control than a tune....they must be set up right.

ok, so my last question to you is this. are ALL of the colored hardlines required?. Currently, the only lines that are hooked in are the ones you see in these photo's. (Red, Green, White, Black) Not hooked in are, (Pink, Blue, a long black (wich went to intake i believe) and a short black one). I'm running a stock WGA and aftermarket BOV. Stock turbo with Block off plate. These links are where you can see them at Photo bucket.

In image 1 there is a red and black wire there among the vacuum lines. Thats for my meth injection, so dont mind those lol.
Image 2 you see the Black, Green, Red and White feeding out. The Red as you can tell leads to the cold side pipe. The white, off to the "TIP".
In Image 3 you see the black line headed strait to the WGA, and the green feeding to what would have been the Turbo housing. BOP instaled and nipple over that T side. At any rate, sorry again to pick your brain so much. Thanks again.
Cheers.

Not the best place to ask that question, the SRT4 pros are here:
