If you alter these tables incorrectly you can mess some **** up. I actually changed mine once to a different table that I found on another 04 denali. I did this unknowingly, luckily everything was fine because it was a GM table I guess. Anyway I did notice a difference in response between the two but also learned from many others if you just blindly start changing this table you will have problems. That is the extent of my knowledge on it, if you do a search on HPT or EFI sites I will bet you find horror stories.
