Hey guys,

Stock Map 0 2011 E92 N55, only has BMS intake, is not hitting target boost.

From the log, I see that AFR is all over the place - not sure if that's normal during WOT?

I've cleaned the MAF and nothing has changed.

Has anyone experienced this before?

*EDIT*
I notice AFR spikes when I let off gas to change gears - I guess this makes sense to me, but not sure why I'm not hitting target boost? Do you think I have a boost leak, or is there something I'm not seeing on the log?


TRY THIS FIRST This was my problem after chasing $$$$$ wasted

For pipe 16 in this diagram, is there any gasket that goes on the turbo side? Or it's only at the intercooler side?

It doesn't show on realoem, but I believe it is this part?

On the turbo outlet pipe I purchased, I'm pretty sure there was an integrated gasket/o ring on the turbo end.

Thank you guys for the responses. I ordered another OE one that I found in other diagrams, for the N55 F series. I will come up with an update to see if it fits or not
