Well, I know the chips on the VW's are highly encrypted and have to be cracked in order to do any sort of tuning. So basically on my car it has to be removed, flashed, then it can be done through the ODB2 port. Unfortunately none of the tuners that do the tunes have been able to crack the encryption on the 2011's.Performance chips are a thing of the past man. Now basically all tuning is done through the OBD2 port via HP Tuners or other similar programmers. I myself use the HPTuners VPM Suite. They cost about 500$ and come with 4 credits (takes to credits to unlock your vehicle but once unlocked you can tune forever) and its really nice to have around. Adjust every parameter of your vehicle with the push of a few buttons. Although if you get it and don't know what your doing then kiss your engine goodbye lol i've seen people do it and its not pretty. Check your GTI Forum for someone that can tune from around you, normal price for someone to tune you via HPtuners is around 200$.
