    Un-boxed my Stage 3 Twin Disc Clutch AND my Upgraded Twin Turbos recently from GotTuned all the way in Poland. Very exited to try these out.

    Secondary O2 sensors, tuned, still needed?

    On my last car, even though the 2nd cat codes were turned 'off' I needed the o2 sensor installed and plugged in to maintain proper fuel trims, not only did it need to be there but it could not be in a 'extended o2 tricker' housing. Had to be in the exhaust flow directly. I would get +12%-+18%...

    HPFP Question

    Greetings! I have an N54 that we don't really know the history of. Yesterday, we fired it up for the first time in our build and it seems the HPFP is completely dead. And by dead I mean the rail pressure was no higher than the low side pressure, at idle. From what I've read online, people with...

    Buying/DIAGNOSING a 2008 335i | dealer - "it has a fuel injector problem"

    First time taking codes from the 08 335i I just picked up ‍♂ Was told it had bad fuel injectors. Barely could touch the throttle at first and didn't wanna idle smooth at all until it warmed up. Ended up changing bank 1 plugs, coils, and injectors..Definitely made a huge difference. Links below...

    2E7C - BSD data bus communications fault

    Quick writeup on my misadventures dealing with this stupid fault code A few months ago I got randomly code 2E7C BSD comms fault. Cleared it, went away. It would come back and eventually got worse from intermittent to present all the time. It can be a royal PITA to diagnose especially if it's...

    Exhaust theory on N54 & turbos in general

    I wanted to talk exhaust theory and get some opinions from people: I've been reading a lot on these forums and it seems that most people are content with the stock exhaust (modified or not) or go with single 3" systems. This kind of bothered/confused me because I always read that the lower the...

    Technical Spark plug indexing

    Disclaimer: this thread not meant for debates on whether there are any hp gains from spark plug indexing When it comes to spark plug indexing I've heard 2 different "correct" ways to do it. Gap facing intake, and gap facing exhaust. Traditionally, domestic guys and NASCAR race teams have...

    My N54 FBO garage build (built motor at 113k)

    I have been slacking getting around to posting on this forum, so let me give a quick synopsis of my N54 experience thus far. Almost a year and a half ago I finally found the e92 335i I had been relentlessly searching for. It was in Ga (I live in Fl), but that didn't matter to me. 6spd MT black...

    Stay Away From RFP Tuning (aka Dean Fuhriman)

    I’m making this post to warn people about RFP Tuning (aka Dean Fuhriman), who has been “tuning” for the N5X community now for a few months. He has a history of screwing up people’s cars, and even bragging about it on Facebook. My first experience with him was Sept 16 when I inquired about his...
