Hey everyone! Hoping someone can help me out and just point me towards the right direction.

I have an E92 ‘11 N55 335i around 88k miles. I’m having issues after being heavy on the gas after a couple minutes or after 20-30 minute drives, I start to have random backfires. Limp mode, like if something is going wrong with fuel for sure.

This is a Mix of codes I’ve had during the limp mode, regular driving, some shadow codes. “2BE9, 2C01, 2BDE, 2BEF, 2BF0.” I’ll turn my car off and driving slow I’ll get home just fine only with “2BEF, 2BF0.”

I’ve changed out the following
Spark Plugs to colder NGK colder
Dinan Coil Packs
Stage 3 LPFP Bucketless.
I’m currently tuned to Stage 2+ MHD, upgraded intake, catless downpipe, fmic, cat back, stage 3 lpfp.

I still have the car symptoms anyways after all these changes. Should I just go and get a new HPFP? The $1000 from FCP euro is going to hurt but, what else can I do.

Some people said check the FPR, but I changed it out with the LPFP I got from another car.
