I'm thinking about using the stock pcm, but I don't know if i would take a chance with my computer and wiring harness. It looks like it has been sitting outside for a while.. Plus the holley you can go from e85 to gas and run meth injection and it will tune it's self... If i run a stock computer and harness i will have to take it and have it tuned and around here it's around $500 then if you buy the hp tuner or efi live that's another cost. How often do you have to tune the stock pcm? Will it adjust automatically when boost is applied?
