Day 1 with the VT1-445
Well, I just got my Z4M Roadster back from the shop with the VT1-445 installed and I'm loving it. BeeDub was right, it drives like stock until you boot it at high rpms, then its scary. Besides performance, the only think that I notice is the whistling sound from the supercharger at the lower rpms, with the pitch increasing with rpms of course. It is quite audible with the roof down, but not annoying. I'll try to do a dyno run in a few weeks when I return from my travels.
