The limit on our engines is the the MAP sensor only reads to 22-23psi. Most tunes run 20 psi on the stock turbo because it runs out of breath on the topend. Looks like that will be the first limit we'll run into with upgraded turbos. Which will be a problem because nobody wants to support rescaling the pressure map for the 4 bar map sensor newer BMWs use. I asked. Fuel will probably be next after that.

How are you liking your Pure Turbos, what kind of differences did you feel going from stock to upgraded turbos even though you're on a stock tune?
After seeing this thread -
http://f10.m5post.com/forums/showthread.php?t=1267910, I was talking with
lfelunden and he said it's not needed on our platform because he claims he can boost beyond the limit of the stock sensors (which I'm guessing is ours since he mentioned it) on the MEVD ECU only.
