Hello, I'm after a bit of advice. I have an f30 320i with a superchips remap, which is great. But the car does not accelerate as well in 6th as it does in any other gear. It's quite noticeable. I even timed it from 50 to a higher speed and it's quicker in 7th. I've spoken to mechanics, gearbox specialists, superchips and the guys who did the remap and no one has a clue or can offer any explaination. I have even had the gearbox adaptations reset but no luck. I'm tearing my hair out on how to get this sorted. Has anyone heard of this before or have any recommendations who can help? I'm in NW. Cheers all
