extent port on 13bt s5 rx7, using standard cpu. need help
hi guys, i recently got my s5 rx7 rebuilt. while doing that i also had it extent ported. would anyone know if there will be any problems. running lean? not enough fuel for the rotors. could i still push my car to redline? getting after market cpu in a couple of months, in the mean time can i do anything to the car?

The stock ECU already runs pretty rich.
Unless you're running way too much boost (over 10psi?), it should be fine.
The primary load sensor for the stock ECU is the AFM.
Since the AFM can detect the increase in VE due to porting (i.e. increase of air intake), the stock ECU can compensate for the porting no problem.
