I really like the VR tune on my 2010 turbo - it has completely eliminated the turbo lag. I had difficulty installing the tune via the handheld device and ended up shipping the ECU to VR so they could load the tune, which gave me an opportunity to drive the car for several weeks w/ just the IPD plenum installed (I ordered both at the same time and Austin from VR gave me a good deal). The car seemed to breathe easier w/ just the IPD and coupled w/ the VR tune the car has been transformed. In Sport mode it's almost too much speed all the time. Talk to VR about just getting their tune w/o the IPD - I think they'll shoot straight w/ you.

Best of luck!
