Been off this forum for a bit. I've been seeing a lot of you guys going with BM3 tune. Is the RC GTS black tune a thing of the past? That's currently what I'm running with no other mods other than a drop in air filter. Currently looking at muffler options and possibly catted downpipe. So is the BM3 far superior over the RC GTS black? Or is the fact you guys are running an aftermarket downpipe the reason you went with BM3? From the looks of this thread, a downpipe is needed to progress to the BM3 stage 2 tune. Lastly, I paid $600 for my RC tune, is the MP3 similar in price?
