Hello fellow BMW enthusiasts! I am running into an issue with my F32 randomly going into a limp mode and shutting down the engine shortly after. In the majority of cases, I am able to start the engine and drive after clearing the error memory. These are all the errors from different...

hey all, what's the best lpfp upgrade running on a stock ekp? I've seen that some folks even have voltage problems running a walbro 450 - let alone a dw400 or wb525; although I'll only be running 93 pump so my flow probably won't be as high as it would be with any ethanol. fuel it has a stage...

Disclaimer: just got the whole shebang installed last weekend, currently investigating some minor hiccups possibly EKP related. Will post full DIY when it's fully sorted. Is working fine now. About 3 weeks ago I started putting together a DIY stage 4 fuel system. My goal was for this to be the...

Hi guys, recently my stage 2 pump wasn't keeping up on E30 and around 22psi of boost on GCs. It was diving to 49 psi which in turn dropped the hpfp as low as 5 (750 psi) sometimes. One product was suggested to me but when I looked at it I thought a DIY looked better. I bought a hydramat for...
