And with that much boost, I highly recommend the GT500 Fuel pump kit. You are more than likely runnning out of fuel pump.
KB says their set up for the 07 is fine with just the BAP and stock GT pump. A few other mustang tuners say the same thing. I for one just don't buy it. EVERYOTHER twinscrew manufacturer says upgrade your pumps. I also don't like the price hack for the GT500 pump kit almost $800 from most places. A price tag I just can't afford right now...as for the tune, I trust KB's tune, the vacuum switch is fine, the boost lines are fine, the bypass/valet switch is fine, the BAP is fine (I think). Its pretty much a plug-n-play set up. No cockpit controller, just a preset resistor in there for "on/off".
