My Tigs booked in for the 29th to have stage 1 ECU, DSG and pop and crackles tune done with etuners motorsport. I am putting in a BMC drop in filter also. Etuners said if I didn't like the DSG tune they would revert it back to stock at no cost.

Will see how that goes then might do the CTS intake, downpipe and stage 2 tune.

Benefit with a custom tune is that you can have it as aggressive or safe as you want, with generic you don't have this option.
