P3cars just recently came out with their gauge setup for the F30 so I had to order it. Should be here by next week. Here
is some info on it if you guys are not familiar. Basically it is a real time gauge that goes in your left air vent and gathers the data from the diagnostic port. You can display boost and a wide variety of temperatures from intake to egt. It also has the ability to read faults as well as provide a recall and shift light function. It really is a trick piece and I can't wait to get it.
