Still waiting on my Pettit Unlimited ECU. Which should arrive any day now. Is it safe to drive/boost on stock ecu with boost set at 10psi or lower? Or should I just drive the car home...not hitting any boost & just wait?

Full ported Non-Seq with block off plates, SMIC, Fuel Pump, Intake, Exhaust. etc. *Leaving stock midpipe in place till ECU arrives.

Thanks guys. Input always appreciated.

 

PowerFC would be a much better choice, haven't heard great results from Petit ecu even being safe trying to hold at 12 psi.

Seems to be safe above, do you have a boost gauge hooked up? Just purchased?

 

ECU won't matter when "trying to hold boost" as the Pettit and PFC will both natively use the same stock solenoids as the stock ECU to control the wastegate. As long as the boost is 10 PSI or lower, you will be fine.

 

I meant for safety/drive ability. I know it won't creep.

 

It should be ok at 10 psi as long as your injectors are stock. The stock ecu runs on the rich side.
