I am in the process of turning my 2001 Jetta TDI into a bit of a sleeper. Up until now it has been all stock except for the 1" lift kit. I have just installed PP520 nozzles and had the injectors balanced and timed. By next week I will have a VR6 clutch installed, a Malone Stage 3 tune, and a DG racepipe. I am also having a Boost Guage installed. My concern is that I hope I don't blow up my stock VNT-15 turbo. I plan to eventually upgrade to a VNT-17 but I hope I can hold off on that a while. Am I going in a good direction? Any opinions? Thanks...
