That's funny. The cars you just mentioned are exactly what MRauburn (the owner and operator of Stangnet) has. A 2001 S/C'd Bullitt, a '04 Mach1 road racer, and a '85 Stang.
What MAF? 90 mm Lightning, Pro-M...(this is more of a future power upgrade)
What fuel pump? Wahlboro? Cobra? Returnless systems are touchy with fuel pumps.
Custom tune or mail order?
