For a bone stock engine - the GM electroncs does a good job. Limequat has a wiring sheet how to wire in the GM electronics to an older vehicle. 2 items to think of here 1) the pcm needs to have a bunch of stuff turned off by someone who has HP tuners box, and the drive by wire gas pedal must be used. The same PCM also runs the 4L60E tranmission.
