5 stars: Had some problems trying to get the licensing but it all worked out in the end and left me really impressed with the support for the app and how quickly they respond to concerns and questions. If you thought your Bmw was fast before stock, well you’re in for a suprise considering this changes the car completely power wise while the engine stays running butter smooth. No Problems or hiccups so far, 2014 Bmw 435i with 39k miles
5 stars: I had this on E90 and now F30 335i. Hands down best and most smooth tune I had considering my experience with others. Customer service is top notch, those guys are quick to responding to emails.
