Is software only worth it?
Just got a 2011 M3 coupe. I'd like to keep the car stock mechanical wise (no aftermarket intake, exhaust etc), but want to squeeze out a little bit of extra performance. A local tuner is willing to do a custom ECU flash with Dyno for aound $800 (no guaranteed numbers, they have the software, but this will be their first e92 M3 tune, so will be some kind of an experiment).
I understand that these NA engines will not have big gains from software, but do you think it's worth a shot? I'd be happy if it can give 15 whp and improve the lower end.
