M2 regrind

Wasn't too happy with my M2 fuel pin. Too much turbo lag, so I regrinded it. Pulled out the old Drimmel port and polish kit and removed the hump. Looks closer to an M3 cut now. Big change in power, a lot more even with better low to mid range throttle response. No more lag at throttle up or surge when things finally caught up. I don't have much for mods. H1C modified with a GDS 60mm compressor and a 16cm2 exhaust housing, a BHAF, and some light pump tuning.
RIP 91.5 W250 5 speed. The great experiment.
92 W250 HD 47RH with Compushift. Upgraded H1C to 62/60/16, Scheid Lightning VE, 60# valve springs, DAP 7X.010 injectors, 4" DE exhaust, home made cooler tubes.
01 2500 "the work truck".
