Check engine doesn’t turn off when I flash your tune
Hello,
If you are getting a CEL due to having catless downpipes, then you did not select the option for disabling the Catalytic Monitors in the flash options. If you don't select 'OFF' on this it will continue to throw a CEL (See here: https://i.imgur.com/JlKn5cy.png). If you've already done this then you have another issue and need to read codes and see what is causing the CEL. BM3 doesn't disable CEL for anything else.
Feel free to email us or Bootmod support if you have additional questions. Hopefully you'll consider updating your review after this.

UPDATE: As suspected, customer is getting a CEL due to having bad O2 sensors; not for having catless downpipes. For obvious reasons, BM3 does not remove CEL for damaged O2 sensors as it would be a massive issue not knowing when your O2 sensors go bad.

Just love the MST air intake, have it on a 2018 b48 330e. The sound is amazing and it just make me smile driving.
Honestly I’m disappointed I order my tune 16 days ago and I’m still waiting for the cable to actually be able to tune my car
Completely satisfied with my purchase. It was a 5 minute setup with registration and flash. My biggest thank you to the wonderful support and team over at MRM, to help start my B58 540i build!
Ive been contacting you guys about maybe a faulty pump and gotten no response but dorch is handling it for me
Great build quality. Highly recommend. Kern did a before and after video while using this and it keeps things cooler. Yes you can powder coat it
had an issue with my order, talked to owner, and he resolved issue quickly and professionally.
worked exactly as advertised and shipping was fast!
Perfect fit really quality so happy
I would like to if there were better instructions on how to install it, and adjust it, when replacing also recommend replacing the flex play as my vehicle started to vibrate after installation
Just make sure to buy a new gasket that goes in the slot on the downpipe where it connects to the turbo! Looking to get fueling mods soon!
Super great the results only adjustment that i can share is just the delivery can be quicker but other than that is awesome
The product is good and has no flaws
Great piece of metal! Real opens that throat
It’s a great product, easy to use. Very user friendly and would definitely recommend.
EXCELLENT PERFECT FIT AND MORE STRONGER
This turbo has made it very easy to turn up the power and has quick spool response making it ideal for a daily driver. Perfect amount of power on e50. I’m RWD in a 2020 m240i stock tire size and it hooks with the right tires. Anymore power and you won’t hook without slicks. Plus if you don’t plan on building the transmission or motor than this turbo will keep you in a safe limit.
Definitely plan on working w/ MRM again
Came on time, and works great boosted the hp on my b58 by like a 100hp with my stage 2+ tune
I ordered a B58TU pump and so couldn’t be more impressed with the store. Great shipping times and customer service, for sure will be ordering more from MRM Performance soon!
I need to learn to read better but I made it work on a 2017
