Anyone else interested in the new BMS stage one piggyback for the n63?
Terry makes some conservative, reliable and highly effective tunes. I installed the JB+ with a drop in filter on my 2010 (n54) 135i and its been a home run. I run it around +2.75 boost and issue free for 2 years.
I think he's looking to replicate the performance results of the JB+ for the n63 which in my opinion would be just right. No need to wait for the factory power bump.
