there have been a few guys out there with stock WGA's who have been able to hold 13-14-15psi by redline, especially some S1 guys.
I have an 03 srt-4 (solar yellow)
which is stock, or atlest thats what i think, and im getting 14-15 psi to readline. I got this car used in june of this year, only 26000 miles and great condition. I stay in so. cali and of course can only get 91 octane. But my car did drop to 11-12 psi one time and i took it back to the dealer and asked them to fix this. Its now back to 14-15 psi and they never wanted to tell me what they did to it. I know it was a boost leak though, im surprised the dealer didnt want to tell me what it was though.
