Overboost on stock?
Hey guys, I'm looking for some help with my 2011 335i Xdrive with an n55.
My car is overboosting on stock software, the only modification being the upgraded charge pipe as my normal one exploded. I even flashed my car to the latest DME software that I could find(8684970) on my car to be assured that I wasn't flashed or anything. I also have the Alpina flash if that matters. Here is a log of a run:https://datazap.me/u/guibibi/overboo...og=0&data=4-19 Any pointers on what I should check to fix this problem? HPFP was also replaced not long ago if that matters. Also forgot to add that at the end of the gear, I got these codes: View post on imgur.com Last edited by Guibibi; 09-20-2018 at 05:38 PM.. |

Your wgdc% is sitting right around 30% during the pull so don’t think you’re actually overboosting to 21+ PSI. Just guessing, but could you of possibly selected 3.5 map sensor option by mistake when you flashed stock?

I would think you would be able to create a test or run a test using diag software before throwing a part at it to see if that helps, no?
