I know the stock ecu disables the secondary injectors at higher boost, and I know you can buy a jumper harness to dis-able this. But I'm wondering if the safc bypasses this and allows the secondary injectors to function at all boost levels? I just bought this car and I'm still trying to learn everything I can about how its setup. Thanks for the input.

 

your speaking of fuel cut I assume? If your not running the stock ecu it won't be there. I have a FCD that fixes that.

 

anothing over 8psi and the stock ecu cuts fuel either a aftermarket EMS or a FCD chip is needed. (fuel cut defender)
