I purchased an SCT X4 Tuner from Texas speed performance. I tuned it after I put of a cold air intake from Roto-Fab. I took the speed limiter off, changed the fuel trim and bumped it up to around 2-4% to accommodate for the extra air the intake brings in, but I also thought that you can increase the rev limiter past 4000rpm. I double checked and it didn’t give me any options to do so. How would I go about purchasing a revised tune? I know I would have to data log, but I’m not exactly sure how to get with the SCT. Also I adjusted the shift pressure to 25%(all the way) and I’m experiencing a weird delay when shifting from 2nd to 3rd gear using the paddle shifters. If anyone can help me out and tell me where I can go about revising my tune I would appreciate it greatly👍🏻🇺🇸
