Just completed a Remote Tuning on my '08 M3 - Stage II with aFe InTake Kit and aFe Mach Force-XP HFC X-pipe. Love the results. The Cold Start Delete in particular is great, no more bucking and brutish noise (well, until WOT that is).
On the street I can't say that I feel any additional power in the seat but it does drive smooth through the power band. It'll be spring before I really get to stretch its legs on the track; in the meantime, looking forward to a winter of tail wagging.
Thanks Mike, look forward to any enhancements coming down the pipe (pun intended
)
