Very nice set-up! I have a very similar combination. Our heads, cams, intake, and plenum are the same. My car made 573WHP @16lbs w/ a 70mm MP Turbo and I have been looking at upgrading to a Precision 7175 or 7275.
What rpm do you start seeing boost? What RPM do you see full boost? How does your that 7275 respond to shifts under acceleration? Do you have a Dyno graph you can share?
Thanks
I start seeing boost around 3100RPMS and hit full boost by around 3800RPMS. I am usually too busy watching the road but I have minimal if any lag after shifts.

Very nice Kerns, for your e85 are you using pump e85 or do you go through VP or something like that?
