I have a 1991 Z28 camaro 5.7L
I have the following mods on the car:
MSD 6AL, MSD COIL, MSD 8.5 wires,MSD Rotor and Cap
52mm BBK Throttle Body
Dual K & N with Air Foil
Flow Master Exhaust
Jet Stage two chip
BBK Adjustable Regulator
Ford Racing 24lb injectors
My question is do I need to get this car pro tuned for the ECM or should the computer with Jet chip compensate all my changes?
Also does anyone know what my fuel pressure should run?
The only other add on I'm going to do is headers.
Any help would be appreciated!

 

I would think a mail order tune would suffice. Unless you want to spend the money.

P.S. Welcome to the board!!
