Salih, a TCU stands for transmission control unit. A reflash would result in quicker shifts.

Hey Guys,

I'm looking to change the headers on my 997tt, it has modded VTG's with plenty of other stuff, but i'm in need of a better throttle response with better spool while not losing at high rpm. I did some research and got 3 brands which seems to be the top 3; GMG - AWE - Switzer .

Which one would you recommend more and why? I'd be glad to hear your personal opinions and experiences.

Thanks,
