2008 bmw 335i targets no boost 3500-5000 rpm very in frequent about when it does or doesnt target boost. does this on multiple tunes some worse then others like the rpf v12. tunes or the ots mhd tunes, ive even played around in tuner pro with the load requirements but havent gotten anything to work. it does this a little on the stock tunes but not as bad when im trying to target more boost with the other tunes. once it sees the proper load requirements the car will boost with no issues.
