Performance prior to IC was 100-200kph in 7.8s and a 1/4 time of 12.09s @ 119.7mph. IATS would top out at 140f on the 100-200 runs and the max i seen on the 1/4 was 160f. This is in 50-60f ambients.
Your 1/4 mile trap speed 119mph is m4 CP territory, which is impressive for a N55 stock turbo without meth. But 100-200 in 7.8s seems just unreal - that's even a full sec faster than m4 cp.

We've done extensive tests on a similarly built m2 on E30. The best times we got from 100-200 was 8.7 using short shifts in 3-4 and 4-5. It'd be 0.3s slower with auto shifting at redline.

There was also one m140 with dp and meth on race map doing low 8s. And we believe it was a definitely way faster car than yours.

We respectfully think real world times are only good power indication if you do side by side pull or at least use a reference car. There are too many variances in conditions that lead to wrong conclusion.
