I noticed lately that when i press in the gas from a complete stop the gear kicks in abruptly instead of a smooth take-off.
So basically from a stop, (doesn’t matter if car is warm/cold/hot), when i press on the gas, the car kicks in right away, it’s like having a manual tranny and i let go of the clutch abruptly and the car kicks forward.
it’s not that bad but you definitely feel it, i can never leave from a stop smoothly, it’s always an abrupt take off. The more i press on the gas, the more abrupt the car moves forward. Like a "bang" it kicks in as if the gear was stuck and then it releases.
Once the car gets going the tranny is perfect, it’s only on takeoff.

I took it to BMW, they know that i have a tune, they did a “slip point calibration” and also regenerated the computer “to reset the way i drive” but it still does it.
They are saying that it’s possible that it’s the tune that is doing it on purpose?
The next step is for BMW to re-flash the ECU back to stock and re-test.

any of you have had this issue?
any input is appreciated.

thanks!
