Hi all, I’m kinda stuck and need help.
I have chevy Tahoe 97, 5.7L V 8, 4wd, ive installed performance camshaft procomb set (springs, valves, rods...etc) and cold air intake + exhaust manifold (headers). Now I came to know that after this upgrade I need to retune my engine, I’ve tried with all local garages but they say the software for this car is not available anymore so they can’t tune it.
can anyone help, can I get a software online from somewhere? Is this a fact that this specific software is rare to find?
