An aftermarket engine management will be used also. Cheers TPS is a necessity for working out acceleration and deceleration enrichments. the ECU should work out the fueling from the MAP vs RPM, but if you slam the throttle, it'll go momentarily lean without the TPS, and when you suddenly close throttle, it'll be rich without TPS. the car will drive withouta TPS, but will be more responsive with a TPS.
