    I am looking into getting a BMW 335i and had a few questions. I currently live in Minnesota and was hoping to find an AWD version but if I can't that's fine I'll use the x5 I drive currently in the winter. What I am trying to accomplish is to build a car that can beat most cars on the road but...

    Hello! I know this question is asked quite frequently, but I'd like to hear some new opinions. I have a stock 2008 335i and was wondering what mods to add to it. I'm looking to add more horsepower. I read a bit about JB4 tunes, if I were to only get it tuned which map would be best? I have up to...

    Hello, I recently installed cat-less headers and deleted my SAP on 2000 BMW 528i. My e39 has the MS42 ecu. Is there anyone in the DFW area who can help me install the EU2 tune on my e39? I've been reading through the DIY's on how to tune it yourself but I'm not good with software. Looks like...

    I have a 2009 BMW 335i. Being in California, it isn't easy to get mods that are CARB approved. I was thinking about getting a COBB tune, FMIC, VRSF inlets or BMS dci, a charge pipe, and eventually a new exhaust. What are the best CARB approved mods I can get for my car? I would love various...

    I know there is not much to be squeezed out of these NA engines but thought I might try. Plans are (if I can convince the wife who normally posts here [it's her car]): American Racing Headers (long) Evolve M3 E-Tronic Exhaust Underdrive pulley (need to pick one... suggestions?) Stage 2 tune...

    Hey guys, looking for some advice. Recently purchased a used 2014 Bmw 335i msport with 16k miles. Car looked great and got a hell of a deal on it so jumped the gun. I noticed there were some mods, especially to the exhaust, but dealer told me it was just the m exhaust package. After driving the...

    I bought an unused JB4 Stage 2 module and harness from a friend. Neither of us realized at the time that there are TWO harness types. I have a late production 2012 335xi, and require the Type B harness. Of course the one I received is a Type A. Is there anyone that has a Type B harness for sale...

    So, I'm just learning about all the ways to make my 335i even better and this is my first vehicle with turbos, and my automotive knowledge is very general, etc.. Last weekend I flashed MHD Stage 1 and I'm totally digging it. As I read more about other ways to upgrade I learn about downpipes and...

    So, Active Autowerke says they can code out secondary Air pump! For Off road purposes of course. $200 for just the delete, or add $100 to the $459 tune to combine it. So for $559 I can never worry about secondary air, gain some power and have a smoother running car overall. Sounds compelling...
  19. E39 (1997 - 2003)
    I purchased a used 2003 540i recently. PO installed a Dinan cold air intake. Is there any way to know if any aftermarket tuning was done to the car? I'm happy either way, the car is fantastic and I have a feeling a tune was installed at some point. I found a previous listing for the car 3...
