i was told that replacing the factory 1.8 8v golf computer with one from a gti will improve power/drivability. the model is a 87 8v golf w/cis-e. also i was told that the gti and jetta computers are the same. anyone try this and did it work. i was told that the fuel map is diferent as it adds more fuel at higher rpm's. i am adding a autotech 270 cam, exhaust and i run at high rpm. wouldn't i need more fuel to compensate for the additional air flow? thanks for any info you may have.
