Should I just do a JB4 tune instead? If you were tuning your 135i for the first time right now, what would you use? (I know this is an MHD thread but I wanted to hear from actual MHD users)
I wouldn't let MHD push you from an N55 to N54. There are other options, JB4, custom, Dinan, etc. At least on my car, the latest MHD maps (other than Stage 0) makes the car virtually undriveable. I really hope it gets fixed soon.
