I'm sorry if the similar thread has already been on this forum (didn't find smth).
My car is an Audi A5 2.0 tfsi quattro with APR stage 1 93aki. I have noticeable vibrations under the load on high gears and low rpms. So the gearbox doesn't downshift - it tries to go on higher gear because of big torque (due to ECU tune of course). It really hurts to feel my car is getting this charge on the drivetrain.
Any other ideas about origin of these vibrations? And what can I do with them? Maybe TCU tune will help or something like dogbone insert ...
P.S. It seems that my problem is unlikely to be a priority for the APR to be fixed. But imo decreasing the boost on low rpm will definitely fix this.
