I wonder if someone could give me a hint where to start...
I bought a car converted with an ls1+4L65 from Corvette. What year, don´t know.
But the PCM is from a 2002 silverado truck. So when i compare the tune that i have now in the car, it seems to be more adopted for a 5.3L truck engine. For example, Ignition is around max 17*, but the corvette has around 28* ? When i do a comparison between a stock corvette tune and my tune it finds 255 diffrences.
Where do you think i should start? I don´t mind reading, and trying stuff, but it would be nice to have a suggestion where to start....
(And no, i cant ask the builder of the car, since i bought the car from his widow... )
