Really love reading threads like this!
I reverted my E90 M3 back to complete stock. Doing a bunch of engine maintenance on it, then plan to dyno stock and every step of the way with the mods to follow.
Are you able to source the DRF files for your stock and full runs from the dyno shop?
When I went from stock to Evolve XPipe/Stage 2 Tune, my car gained roughly 45whp at max values. With how sensitive these motors are to IAT, EGT, Oil Temps, did you do any data logging to see what ignition targets you were hitting?
