I don't know if this helps but IMHO. Vast is the way to go. There are several people using there trans files. As you can see for the 4.2l there is no other tuner that could get the car to rev past stock. I know the 2.7t guys don't need the valve body any more when you do the vast tip file. in the end even if you do the level 10 valve body you still don't get the TCU to shift the car any faster. There are few tip guys that have said the VAST stage 3 tip file is faster shifting than the valve body from level 10 not only that but you save 400+dollars. if you do the complete ECU and TCU you are looking at REAL power. from what I know about the vast 2.7 software they have the fastest S4 (full interior) in the world 11.1 at 130mph from that to the GT600 car they have I would suggest you talk to the vast guys...just thought I would share my video as they made my car run like a totally new car and I have a N/A car
