I just had my 99 M roadster dyno tested in preparation to upgrading the exhaust and cold air intake. To my surprise, when we ran the test in 5th I got all the way to 150mph at redline (both on car's speedo and the dyno's).

I was expecting the computer to shut it down at 137, now I may reconsider buying the ODBII reprogramming from Dinan or Jim C.

I'll post all the results when the mods are finished, but stock HP was 211 at the rear wheels.
