..SRT-4 vs GT pcm...
...if the PCM is programmed differently for the SRT-4 and they are able to hold the boost through out the rpm range maybe we ought to try switching the PCM's and seeing if we can get the high horsepower readings to the wheels on a PT.

we have not been holding boost up to redline. If we set it to 15psi, it drops to 13psi after 4k RPM. Read my E.D. Mod if you want to hold boost on my site.
Also try putting a check valve on your stock surge valve so it wont cycle. This causes boost to fluctuate when you raise the boost. Its a good idea to have an aftermarket BOV also when disabling the stock surge valve. The PCM i beleive hooks up different than you guys. We have 3 plugs on out pcm and they are coller coded in black, white and red on the ecu connector ends.
