Hey guys, I've got a '07 GT Mustang w/ BBK ceramic long headers, BBK shorty X pipes, Corsa exhaust, and a Stage 2 Roush supercharger ( http://www.roushperformance.com/parts/Ford-Mustang-Supercharger-2005-2009.html). I'm not the original owner so beside an Exceddy clutch, Hurst short shifter, and 3.55 gears, I don't believe this car has any other (performance) mods.
When I down shift and tach it to about 4,000 RPM's or just accelerate hard in general, the car is not getting gas and sputters. I'm getting about 15.5-16 MPG average (and I'm not typically driving it hard) so fuel is going somewhere. Always use 93 octane. Using the tune by a local Roush dealer who sold and installed the kit.
Any suggestions on where my fuel shortage is or what's causing it to sputter at high RPM's? I'm not a mechanic so feel free to explain in detail. Thanks for any input! I hope it's something simple.
