MHD stage 1 tune
so about a month ago I flashed the mhd stage 1 tune and have just a couple of questions. one thing I have noticed that I cannot do a burnout now? im a auto 07 335i. before I could just power brake and burn out with no problem, now when I try the wheels will spin for about 2 seconds and the power gets cut. anyone else have this problem? I went to the dragstrip and was going to warm the tires up a little to try and help out with loss of traction but couldn't do it. next question is I would like to know how many people actually hit target boost and how early? seems to be a little laggy and not always hitting target. here is a log to check out from a stop to 3rd pull.

Had the same problem. The increased boost is pushing past the stock dv's. Replaced charge pipe with Cobb unit and the dv's with a pair of Hyperboost and now it will cook my 275's.

woah that boost curve is all over the place. Did you recently install a FMIC? I know I had a minor boost leak at one of my couplers when I installed mine.
Good luck figuring it out. 13psi seems low as a peak ever for stage 1.
