Well I just got into a 2011 335i with the premium and sport package. I've looked around on a few sites and seen quite a bit about the JB3, JB4, and downpipes. My car is under warranty and from what I've read, just about any tuning done to the car will throw a code and void my warranty. What are some mods I can do to my car without voiding anything? I don't have a problem with removing them before I take it in, but is there anything else I will need to do to be sure I stay in my warranty? Thanks for any help!

you wont void your warrenty if you remove it all prior to dealer visit.

Each sticker will give you 1HP, it it's nice and rainbow colored you'll get 5HP. Will not void warranty.

Haha! J/k

Yes, use the tune to clear codes, then remove the tune. This goes with mostly any mod, but as you expect a Downpipe would be a PIA to keep taking off.

I have a giant NOS sticker that covers the whole rear window, and I put at least twenty moth balls in my gas tank everytime I fill up. Needless to say she's already quite a beast.

HAHA. joke.

Seriously though, if I get and install the JB3 will I just have to plug it in for power then take it off before the dealership? Or do I have to buy something to erase the codes also?

I'm assuming that you have a N55 engine. If so, you can get the BMS JB3 N55 Stage 2 which would should get you about 350whp. It installs in probably 30 minutes or less, read/deletes codes, and has many other features. There is a lot things actually available for the N55.

Just hooked up a customer a while ago with JB3 N55 Stage 2, AFE Intake, AR Downpipes, Evolution Racewerks FMIC, and Rogue Exhaust and it's a beast!

Check out the little video he made below:

Your best her probably is to grab the JB4 Stage2 as it comes with code reading and clearing and full steering wheel controls, so its a pretty awesome upgrade to the car and install is pretty simple. I would budget around 45min the first time.

When going in to the dealer for maintenance you can set it to map0 (JB4 off) and if going for major warranty work you can just remove it.

Shoot me a PM if you need more advice or have any questions.
