My dyno plots

Mods are minimal and are S1, K&N drop-in, AGP WGA, TurboXS HPMBC, JMB UPP w/ HKS SSQV.

This plot is off my stock (w/ K&N filter) run back when I first bought the car versus my highest new run.




This run was my new baseline versus my highest run




This run is of all 3 pulls I did today.
First baseline pull was with boost levels spiking to 16-17 psi and dropping off around 13-14 psi @ redline.
Second pull was with boost raised to spike 17-18 psi and drop to a steady 15 psi @ redline.
Final run was with even more raised boost to spike 18-20 spi and dropped off to 15 psi @ redline.

Its ok. I was expecting more but I have a small boost leak and no mapclamp so i think the PCM was pulling timing on the last two runs, otherwisae power would of been slightly higher I'm sure.

The real factor is a boost leak I believe. That plus coupled with the PCM pulling timing is my main reason why I think I wasn't making what I thought. Its a easy fix. Map clamp and return line = tuning fo mo powa

They are common on any turbocharged car.

Its funny to see people on .net talk down about SRT4 because they have "boost leaks". Hell, every turbo car owner I know deals with boost leaks. Doesn't matter if its a SRT4, a turbo RSX, stock Supra, old diesel turbo work truck, etc etc. Its just part of owning a turbo car and doing the basic maintenance. Should check for boost leaks evey oil change or so.

Nice #'s, and as predicted, stg 1 max out on 17 psi, any higher and the pcm will start to pull timing. But I'm glad to see the dyno results that would prove this theory. Thanks for the post, and like most peeps says, with your setup, it's not really that far from stg 2. You must have big time traction problem or wheel hop with first gear. I know I do.
