What year car is this going in, IIRC, you cant redo the newer(58x) computers to work in a car application, unless they came from a car.
Get yourself a 5.3 or 6.0
an ls1 computer and ls1 harness for the correct trans
have the displacement adjusted in the ls1 computer to 5.3 or 6.0 to keep the computer from running the engine lean or rich. Anyone with hp tuners should be able to do that, that should get it running pretty well, but id definitely go for a full tune after.
And to whoever asked, my car is all straightend out for the most part, still have to wire up the cruise, total PITA. But it doesnt keep me from driving it everyday.
