Hi and congrats, I have a 2011 mn, love it and I have never had a problem with it at all. First things I did is upgrade the suspension 2" lift and did a remap. both made a massive improvement. Provent catch can is going in this weekend.
My remap was $1250 and have 162 HP now. Could of gone higher but I didn't want to push it. I haven't worried about the EGT delete as the remap helps reduce the amount of exhaust going back into the inlet manifold. Plus I don't have an issue with fault codes. Seems like a lot of money but the difference in driving is a lot. Got mine done at opposite lock
