What year model is the H2? If nothing else I have quite a bit of experience with programmers since i have had one on My 99 Silverado since i bought it new. If it is an 2005 the only one that i can absolutely tell You will work without damage to 2005 is put out by comp cams and i think they named it Fast Flash Handheld Programmer. If older then I have had more experience with Hypertech since i'm only 1 1/2 hours from both brands. Hope it helps. OH, I agree completely with previuos replies go with programer not a chip. With programer You can adjust speedometer to match tire etc. there are just alot of things you can have control over with programer.
