Can't decide which turbo to go for, currently have the Garrett pmax g25-660 but I've gotten bored with it. Where should I go next? Car is rod and piston built, mpi, brushless lpfp, fbo, e85. Thanks
I recent test drove a 2018 R to upgrade from my mk7. The car is completely stock besides a IE intake yet it has a ton of turbo flutter. The dv is still plugged in and stock, and the car isn't tuned. From my understanding there shouldn't be any flutter at all. Any ideas what could be causing it...
