The only mods i have done is full exhaust including midpipe and intake. Can i throw on a Petit ECU and run around 14 psi on stock intercooler and stock fuel system? Thanks

 

Your running a mid pipe on stock fuel? Say goodbye to your engine because it is going to be broke soon. Even with a pettit ecu your asking for trouble. If you keep that mid pipe you need to get a larger fuel delivery system. Seriously take the midpipe off until you get that fixed.

 

TAKE OFF THE MIDPIPE...or don't drive at all until you get the ECU installed. A pettit ECU is supposed to be fine with a midpipe, but personally I would only run a hi-flow cat or normal cat with one, never a midpipe.

edit: Also get a boost gauge on there, you should see your boost is above 10 ( I woudln't even test it, just get the ecu first and then see where you were at). If you are above 10 AT ALL, then you should never drive without a new ECU

 

so i can put on a cat and throw on the petit ecu and run 12-14 psi no problem on stock fuel and intercooler?

 

pettit says just to keep it at 12 psi. if everything else is healthy and you have a boost controller (you will need one) 12 psi is FINE on the pettit ecu with a mp
