I hate reading this. At 12 psi, an AT won't even hang with a WRX? That's a disappointment to me, seeing as I am looking into buying one. My current car (Dodge Omni Turbo) eats WRX's alive. They'll get me acrss an intersection, but once I am 1/2 way tru 2nd, they are reeled back in, and by 3rd, they are diappearing behind me.
Also, I keep hearing that 15-16 psi is the max for these cars. Is that because of the fuel system's limitaions, or the turbo's? I know my own car's stock Garrett turbo can pound out over 25 psi, and I have been running it at 17-18 psi for years...the 1st 3 of which I surged the hell out of it with no BOV (turbo dodge intercooled cars didn't come with BOV's till '90), then finally I added a TurboXS one.
