Doesn’t look like hard testing? Why couldn’t that just some reg dude running

Because of the potential locked Ecu on my 2021 I got JB4 and EWG. Different map with ewg? Or does it do it’s thing automatically. Will go to a custom tune when the gurus figure it out.

Just did the air box mod. Pretty simple. I am expecting zero gains just a little more Intake noise. The stock intake path is very well engineered as far as cold air and volume. I can’t see $$ cai doing much Also our engines with out the plastic cover is pretty ugly. Like to see some...

Some good photographers here!! Had it little over a week. Day 2 I tinted and blacked out reflectors. I have a bunch of wedsite open with shopping carts full. Just can’t decide on some some stuff....: Decisions decisions Already tracked once. It will become my weekend/track car...

Had a JB4 on my N54 and i was very pleased with the safety features and flexibility of map 5 I have a 2021 that may be unlockable otherwise I would 100% go ecutec. While i am confident someone will be able to crack it, I do not know if it will be a week or a year. May go with JB4 in...

I am a newbie too. Was debating going M4 as I have owned a string of BMWs. Like you, i like the road less traveled. Still have an e46 M3. so far really liking the feel of this one.

Technically i do not think my 2021 is a A91. That is the "special" edition for 2021 with seat stitching and decals on C pillar. Mine is an A90 but with the newer engine specs and programing. It is pretty nasty stock. Handles amazing on the track- well above my skill level so far. Just...

Newbie..... So can you flash BM3 on a virgin ECU or does it need to be benched first? Former N54/jb4-MHD owner and still M3 so I am aware of the basic tenants of piggy back vs ecu flash

Might be on the bubble... My 2021 build date was 6/20 Fingers crossed
