Hey guys, quick s-10 question. My friend has a 2003 (last year, I think) and he is trying to get a Superchips Max tuner for it but we can only find ones compatible up to 2002(part #2575). We tried one of those thinking it would be the same and its saying "no communication from PCM" why wont this work? Did they really change it from 2002-2003?
