This app is fantastic. Ease of use (simple functions and features), while also having a features that allow even more control. If I had to do it all again, I'd start with XHP. You can feel the difference immediately. This is a drivers mod you can appreciate. Some updates have wiped out my custom settings, so I suggest making notes of all custom changes.

Amazing application, turned my 435i into a beast. I have the pure turbo setup on my N55 435i, and I noticed an immediate difference in power and performance when installing this xHP transmission flash. Shifts are more aggressive, and the extra power doesn't feel like it's taking a toll on the transmission. With the stock software, I felt like the transmission was having trouble putting down the power, but now with xHP it feels so much better. Highly recommend installing this!

2010 535i Msport SAT. I've been customed tuned on MHD with RB1 turbos for over 2 years. I just reflashed xHP stage 3 update with -5% reduced torque reduction on 1->2 shift. The car is so much smoother and even faster. I have much more control with just throttle input, let alone manual mode in Sport. But Sportive+ is pure back road heaven. It's like a whole new character. I wish I could block the 2->1 downshift in altogher. That said, only regret is not reflashing sooner!
