I'm also BM3 stage 1 93AKI, its not bad, but think they need to revise it a bit. they always do, but it's only been out for a couple months so it'll take a little time to get the next release. it's super easy and glad I went that path. Once I get stage 2 I'll probably get it custom done to meet my driving behavior needs. think they poked at the throttle response too much.
