Having tested MHD and BM3, by recollecting data from logs, dyno and dragy times, I can tell that by far MG flasher has the best OTS maps available for the B58 engine. The time gains in high altitude environments (8600ft) and low altitude envs is remarkable, without putting the engine components under maximum stress (from the data I’ve read on the logs testing the multiple maps they offer) which make them very reliable maps. I’ve been running stage 2 for 1 year in a 2018 M240i with 0 issues. Also the app is very well crafted and easy to use. The flash itself is very smooth, and it has great features such as map switching on the fly which is great feature for those out there using pump gas for the regular commute and E30 on the weekends. Their support is great and they always listen an reply to your questions in a timely fashion. I just have positive words for MG flasher and no complains, keep the great work guys.
Awesome platform
Velociraptor man
I mostly switched over to this platform for the antilag options but I began to love it even more because they allow you to play with so many more perimeters than the other platforms allow for. Definitely love it so far
Great product great support
NicOttawa
This product is awesome. The extra power for my B58 is kick-in-the-pants noticeable. I’ve sent them a question twice now and both times responded quickly and helpfully. Highly recommend.
The best interface for B58’s
Marcos_c94
Plain and simple, this is the best interface for the gen 1 B58. I looked at MHD and Bootmod3 and this one was the easiest to use for me. Their customer service is great as well.
