I can read this stuff all day long and would never change my reasons for going with VF Supercharger. Of course TT is faster, I never doubted that, and yes even faster off line with lag, but you do still feel the lag something I don't want. Did my R8 V8, R8 V10 and now Huracan and not one single issue and I still talk with owners of those R8's and still running trouble free. Have 5 friends with TT systems in Gallardo's, Mercie and a 458, not one of those cars finished last season without spending time in for repair. My installs have been done by my local Audi dealership 10 minutes from me and completed in just a few days. Then it's great that the person who installs kit will be the one servicing it. I chose those things over being the fastest, which no matter what you go with you never will be
