Is there a leak or what?

trapahh · 11-16-2018, 10:06 PM

While playing around with a benz around 120 or so, my half engine light can on so i slowed down and cleared the code on my tablet while driving. Car is FBO running stage 2+ MHD v7 map. I didnt have any problems with the car while driving home and everything felt normal. Though, i did notice that when im in high rpms, it sounded as if air might have been leaking out of something. I wouldnt describe the sound as a whistle or anything as such but kinda like a lot of air going somewhere. I check the code and it was 30FF. I also noticed that i am not hitting my boost target. I pulled the car in different gears and noticed that i would reach around 14 but my target is around 16/17. My vacuum seems to be good consider its at -11.8 but i just cant seem to get past 14psi. I will post some of my logs and was wondering if anyone can tell me if i have a pair of turbos going bad or if there is just a leak somewhere. Thank you

UPDATE: I took the car into the shop and my mechanic said he performed a smoke test. He said everything checked out to be alright, nothing seemed out of the ordinary and even put a few turns onto everything. When I got the car back, I still wasn't hitting target. Can anyone point me in the right direction on what to do next please. Thank you

Pair of turbos? Are you sure you have an N55? N55 only have one turbo. Check your charge pipe since you're losing boost.

OP has an N54, not an N55. trapahh you should re-post this in the N54 forum
