Oh then keep the p28 and have it chipped/tuned. This info wouldve helped in the beginning of your post BTW.
Also injectors would be a wise choice.

Oh yea also... Don't drive the car until you get the ecu chipped and at least loaded with a basemap by a tuner that you have told about all the mods on the motor.
Then drive the car to get a street tune, or if you have money tuned on a dyno.
