Does this log look okay?
Just one single pull in 3rd to redline with traction off.
My car is a 2011 335i E92
Mhd stage 2+
FBO
New HPFP
New coil and spark plugs

I'm not an expert by any means, but from my cursory glance, you have timing corrections across all cylinders at low RPM high boost (what spark plugs did you put in and with what gap?) and you hit 100% WGDC to make 13 PSI around 6000RPM with catless downpipes which seems too high to me. Your STFT is also -20% at redline, which is also strange. Is it a fresh tune? If so you might have to drive it a bit longer to let the DME adapt, might need colder sparked plugs or a tighter gap for those corrections or maybe higher octane/higher quality fuel.

I'm on stock spark plugs gapped at .028. My NGK 2 step colder ones get here this week and I've been told to gap them at .020. The tune im running is MHD stage 2+ with a flame map in it so that might throw some other things off too.

Did you get two-step colder N55 plugs? Or two-step colder than the N54 plugs which means one step colder than stock N55 plugs? I don't think a "flame" map will mess with 3rd gear pulls but I'm not sure what exactly your tuner has done.

Guarantee you have a boost leak. Check all connections with a boost leak tester. WGDC should be a smooth increment.

Here's my FBO E92 N55 with HPFP: https://datazap.me/u/jlegelis/v12-xd...-24&solo=10-24

.022 seems to be the sweet spot.

2 step colder for N55

Plugs are a second-order concern - but this is the part you want: https://www.fcpeuro.com/products/bmw...plug-ngk-96987

First figure out why your WGDC is all over the place....

I havent seen 2 step colder plugs for n55 please enlight me.

Sorry I bought the NGK 97506 I do believe they're the 2 step colder for N54

What charge pipe you running and how is the connection?

I believe it's the VRSF charge pipe and it came on the car when I got it but it looks the same the connection looks fine but today I'm going to replace all my clamps with worm clamps

[Tunafish]

Just out of curiosity what would a normal wgdc% look like..

I replaced all my intercooler clamps with worm gear clamps to fix my previous boost leak and just wanted to see if this log looks better?

1 - You are consistently way under target boost.
2 - You are consistently way under target load.
3 - You have an unacceptable amount of timing corrections across all cylinders.
4 - You have an unusually high WGDC compared to your actual boost level.
5 - Your STFT starts to pull an unusually high amount of fuel as your RPMs increase.

Isn't weird that the OP's IAT is flat-lined throughout these logs?
