DO IT !!!!!!!Here's another happy customer for the TVS DSG update. Thanks @BognorMotors . The van is much more responsive, and no more droning at about 1100 rpm in 7th and/or hesitancy to start off from 1st or in reverse.
Now actively considering the ECU remap as well. IMO, an ECU remap is not for more power, but for helping the engine run well.
