@OP there are only a couple of us that hang around the fourms. There is a 1M and 335d owners with RENNtech that also frequent these forums.
About a month ago I was at the RENNtech shop with a local who got a free dyno. RENNtech put the same tune on his 07 E92 335i that rendered a 378 whp (unadaptive) vs his tune that rendered 388 whp w/meth (adaptive) and he was MT
There are alot more of us out there than it seems, its just most dont frequent forums[/
Do you know the whp difference between renntech and Dinan stage 3?
Do you know if renntech is coming out with higher grade tune that requires FMIC?
