Ok, I have done multiple searches here and on the net in general, and I am still at a loss. I have an 87 Firebird with a 350 in it. I was going to put a 400 with TPI in my van, but came across the whole car for less than I was going to pay for just a TPI unit. The 350 runs excellent, so I am just swapping in the whole motor. Anyway, my van is a 94 with tbi. I know that I can slightly modify my harness to run the injectors and all. My question is, what do I need to do to run this engine with my current computer? What will I need to do o make this intake MAP compatible? Thanks again, William
