I personally love I can have more power than stock but not have to run 1 set psi at all times. I can use map 2 only for racing. Map 1 for daily driving. You can datalog and read codes. You can clear codes. No Cel with downpipes installed. I had the jb4 for 3 years on my m4 from 200 miles on the car to 22k with no issues. On the M6 I have the jb4 for about 3k miles so far.
The cons for me is that the limiter stays the same. I can't pass NY inspection without a flash tune. Install is a few hours and a bit of a pain in the a$$.

Thanks for your feedback. To be honest with I had no idea that jb4 didn’t allow you to raise the rev limiter. Plus, I thought that they had a valet mode add on that allows users to switch their vehicles back to stock for emissions testing and for dealership visits. I like the fact that you can switch stages on the fly.
You have far more hands on experience with the jb4 tuner, than many others. Your 3 plus years of experience with that tuner allows you to validate the tuner without prejudice. Thanks for your input. Btw, if money weren’t a problem, what tuner besides jb4 would you have gotten? |

I used Eurocaheged for my w211 E55 before my M4. Those guys were excellent also. I don't see many BMW's running thier flash though seems to be mainly MB using them.
After doing research here it seems that Mission Performance and Bootmod3 seem to be go to tuners for this platform.
