So basically, this guy boosted an M3 to make it run the same thing as stock? Wow! I don't feel so bad about my bunk second gear anymore.
Ima change it out with some BG Synchroshift II (basically synthetic 40w gear oil), and see if I can get it in second gear at 8g's. I dunno why 90w would make such a difference because I could slam 2nd before with BG II. You'd think synchros would actually work better with the extra friction, but I guess too much is bad?
If I can't get it in second at 8000 RPMS with the BG II, this transmission is coming back out of the car again. I've had a dozen problems with the shop that did the work (again) and I don't know if this is even my transmission anymore. It's supposed to be built for this.
