I don't agree with that. The stock turbo, among other things, is intentionally stunted because people were having too much fun with N54s and making M3s look silly. If I were given an N55 car and...

Everything seemed perfect for just short of a month and then it went haywire again. Started car after two stops of a few minutes or less and it sputtered and died twice, "engine malfunction". ...

Thanks, I've also seen different part numbers for them, I'm just wondering about compatibility. Based on searching the manuals may be heavier duty but still fit, which would be fine with me (better...

Are manual axles compatible with automatic cars, specifically 2013 E92 335i xDrive? I'm looking at GKNs because they're OE but cheaper than BMW, and I can't find the rear left auto axle anywhere. ...

Great. Change steering menu 12 to 3100 and the response is great.


All I can say is the same boost is more power with bigger turbos, and "probably" not much harder on the engine.


Better,...

I haven't had engine problems but have had to replace more parts than I expected. Water pump, two diffs (xdrive) and the oil filter housing gasket is bad, all before 60k. The big pro for me as a...

I rerouted power to the boost solenoid wire, and scraped off the paint under the shock tower bolt for the JB4 and PIC grounds, cleaning and electrical lubing everything. Elected not to run grounds...

As far as I know the battery's fine, no weak starts or anything.

I bought the JB4 9/2017.

Re: power supply, you mean the red wire stuck in the fuse socket? Any other connections to check?

No steering controls, "engine malfunction"

Have JB4 and BMS PI controller. Car's been pretty carefree for several months since removing the MAP connection. (Before that got "engine malfunction" hiccups like ten times, could be a coincidence,...

I got the battery discharge message like three times after installing the JB4 but never again. I speculate it draws more power and the DME "gets used to it", but if you always got the message that's...

With just air though, you aren't going to change the ratio of oxygen as you would with nitrous (or just oxygen), so you don't have to worry about tuning or blowing up your engine. Also, not all of...

We have data of 859 psi for stock, and only much higher points for B58. I see circa 2000 psi, and what looks like a little less, but unless the graph is an actual forgery (Why would it be?; Why am I...

If you don't know what the results are how can you say they're not worth it. And I thought it was way more than $200 and already have auxilary fueling.

I thought you were the ace at reading the data, so what's the difference? I bet it's significant, favoring the B58 pump, unless you have further information.
