I have a 2004 Colorado 3.5L with a turbo on it. It was originally a 4L60E truck, and I just swapped an AR5 manual in it. Everything seems fine, except now the truck wont rev past 5k rpms. My tuner was really flaky before, so I bought HP so I can tweak the tunes myself. I have a little tuning knowledge, but at the same point, I'm a newbie to this. Just looking for a little help/guidance to point me in the right direction. Any help would be greatly appreciated! I have a data log and I will attach the tune file if anyone can take a look at them for me.5k.hplColoradov1.0.hpt
