Alright I’m hopping back into the forum life, something which I haven’t been a part of since I used to ride motorcycles. Recently took the plunge and picked up a car I’ve wanted for a long while now. I’ve wanted an E61535xi ever since I ran across several build logs years and years ago. Well...

Hello everyone, I thought I'd take some time to share a build a friend and I have been (slowly) working on since the beginning of this year (2018). I actually tried to make this thread on another forum sometime during the summer, but my post ended up being eaten, and I didn't have the...

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...

So, it's been almost a year since I got the PD unit and installed xHP...over all the PD unit shifts smooth on the PD stock flash but does jerk/lurch and hesitate when using Stage 3 xHP. Clemens said it was due to power levels but mine was the first with any issue with PD and xHP. I been trying...

I am parting out my '10 535i N54 before I trade her in. I have priced the items with shipping except the FMIC as I have no clue what shipping would be. I feel these are fair pricing to include shipping, but if you want to ask less - it would not include shipping. If you are relatively local to...

I'm trying to disable some O2 emissions system check codes to diagnose my car. It's giving me a lot of grief throwing heater, function, system check, etc. codes for the Pre-cat O2 sensors on my single turbo setup. AFRs will lean out and it'll drive like s#&t until the codes are cleared. All the...
