Had my 2010 135i for about 6 months now. Initially I was sure I'd tune, then for a while I was pretty sure I'd leave it stock. Well, I finally broke down, and ordered a JB+. Why the heck not? If it really doesn't throw codes in the default setting, and I can get 25 or so horses out of it, maybe a hair more on 93 octane, I'm now thinking hell yeah. I even upgraded the shipping so it gets here faster. :-D
Definitely didn't want the JB3 or Dinan or anything, I just want a wee bit more punch. Everything else on the car is pure stock, even the RFTs.
Pretty stoked!
