Good afternoon,
I have a 2018 silverado 1500 with 5.3 . I did not realize at the time of tuning that the IAT was reading high and MAF was reading low. I just replaced the sensor and put a new filter in and now truck is running like crap with KR. I am trying to ask opinion on if decreasing maf calibration is all i need or if I need to completely start over. Any help in were to start would be great, new and truthfully cant afford to take it to a dyno around here with the prices after the transmission rebuild and cam going out.
