BMW M4 MEVD 17.2.G Hesitation, Jerkiness and holding in gear after tuning when pushed
Hello I have a bmw m4 here totally stock vehicle and ive tried a couple of tunes on it from two different vendors and get a strange on off feeling and jerkiness when pushed hard on the gas and not shifting the gears like it should its sorting not shifting up when it should
The stock file its fine only when tuned it does it , i expected to scan the car and find missfire codes but nothing at all. Heres the orig and twi tunes ive tried i was just wondering if any experts on these cars know where the issue may lie? thanks |
