@Thewespaul how are you getting your truck up to 3500 in 5th gear? Mine just won’t do it even in 4th it just wants to be over with at like 2900? Pulls strong until above like 2500. And if I shift it will climb really fast in 4th and 5th till then and then it just seems to sign off. 1-2-3rd can climb till redline and then some though. With a r and d 90cc and stage 1’s/ upgraded factory turbo/ intercooler and carter 4070 lift.
