Has anyone piggybacked a FAST system to the stock PCM? I would love to do this. It would allow me to keep the stock PCM for the emissions test, while giving me the flexability of the FAST for my turbo.

 

I did it on a 99 Vortec truck some time ago and it worked out well. Doing it on a F body should be no different theoretically.

 

That's what I've been thinking. I'm gonna look into it. Thanks for the reply.

 

thats what i am in the middle of right now. well sort of, i have cut every pin out of the factory PCM that i don't need, emissions, A/C, injector controls, ignition controls...etc.
however i have hit a few problems with how to make things work together but i think i am getting through it.

I'm running one on my car to retain the factory gauges...that's about it.
