Procharger D1 HO Kit Dyno Chart 4.1 Pulley - Flat power after 6400 RPM

[Toothless]

No fix. Best bet is a GT350 manifold and put a check valve in that line. Or go with IMRC delete plates on stock or GT350 manifold. Or turn boost down to 8 psi and then your curve will look nicer. Or pulley down to make more boost and change shift points back to stock at 6800 rpm.

I sold my car. So signature is old. I had this problem with stock manifolds and cats and after headers with high flow cats. IT IS 100% not an exhaust or cat issue, this is on the intake side of things.

so is there a fix for this problem or basically we are just screwed lol. also you seem to have the exact same headers i have with the same hiflow cats !! have yours caused you any problems.

toothless is correct. that being said i have more digging im going to do this weekend

so i just found out that roush'sstage 2 and new stage 3 kits are lmited to 6500 rpm as well graph flatlines after 6500. i had two people show me there graphs and right at 6500 they begin to faltline as well. Its weird though because alot of cars dont seem to do this. as far as i know .

I'm so sorry guys. I'm just really excited and I think this will work.Will include more information once I get it on the dyno to verify.

Tune related or engine related?

 

[Deadmau5]

It seems to be tuned related.

 

[SolarFlare]

It seems to be tuned related.

So I take it you're going to another tuner.

Sai li? Or mattdiablo?

From what I have read in this thread, you guys seem to think that the iMrc valves close proportionaly based on voltage. I always thought that they were either open or closed. If they are proportional, how are they controlled?
