id have to think you got the wrong trans ratio in the tune then. id call intense up ask then you check your file to see what gears they loaded up. ppl are only human, mistakes happen. if they screwed up id hope they would make it right.
dont drive the car like this, it can kill the tranny if you do have the wrong ratio installed.
if intense hangs you. if you got a local junk yard handy grab a na pcm for your year car, take your sc belt off, run that pcm, see if the tranny is happy again.
i can tune ya, but im all the way up north NJ 5 miles from the gwb. id not drive it that far. i do have a spare pcm for 01-03 i could sell ya with a tune on it. worst case scenario.
