Have not seen anything yet but you should be able to get an idea by looking at mods for other cars with the B58 engine. I’d add though that the M40i has one of the higher output variants of B58 from the factory so bear that in mind when looking at mods.

Dinan has their tune available for the 340i and 440i with the M Performance Pack which should be pretty close to what the X3 M40i comes with stock.
https://www.dinancars.com/product/d4...ries&mid=1237/ They're pretty conservative and their initial dynos had the stock cars at 378/395 with their tune taking it up to 426/463. http://files.dinancars.com/webresour...1655-ST1_5.jpg

Dinan / Burger Tuning
I'm sure both Dinan and Burger tuning will come up with a tune in the coming months. I've been a long term customer of both and a tune is definitely the way to go. Really pushes the car to the next level.

Jesus stock 340is are doing 378 to the wheels now? Thats nuts. 426 with just a tune? Hell a few bolt ons and you're deep into M3 territory without anything even major done.
Nuts. |

Couldn't find much on them except bad reviews and rip off from 2008. Sounds like a scam to me. I'd stick to the bigger name tuners like Burger and Dinan

I have a M235i that was on a full JB4 setup but have since been using a JB+ purely out of simplicity and laziness (removing for service, etc) and have it at max and am more than content with the power. It's fun enough and I'm not thinking about it much. Not to mention how awesome it is for the 1 minute to remove or install.

Can somebody please let me know when Dinan's tune is released for the M40i?

So I had this on my SQ5... it appears they now do petrol as well as diesel tuning... good reputation and the box on my Audi was excellent...
Not cheap though so many will probably wish to stick with BMS / Dinan as these seem to be Proven BMW tuners... https://www.diesel-performance.co.uk...65kw-2998-ccm/ |
