Next time I'll do the research BEFORE posting...sorry
Apparently the FAST system replaces the distributor, intake manifold and throttle body in addition to the PCM and associated electronic parts. But then I saw on Fast's website that they make a kit for a SBC http://www.fuelairspark.com/Products/chrysler/sb/over.asp
Wonder what they meant by "not compatible".
I know one thing I could do is put a milder cam in the truck that wouldn't need extra control but I'm still interested in replacing the factory PCM.
Any other suggestions and ideas are greatly appreciated.
Thanks again,
James

No more rich idle and controlled the mix throughout the RPM range. Well the Apexi died and it's back to running rich. My brother (who I sold the truck to) took it to a speed shop that first recommended a FAST system but then said they don't make one compatible with his truck.
