5 stars: Can't imagine going back to a stock map now. Been driving on Stage 2 for a while, flashed Stage 3 today. Don't bother with Stage 1/2, go straight to Stage 3. You won't lose any comfort on Comfort mode and it is way more fun on Sport+. (F25 N55)
5 stars: I did not think a trans tune would make a huge difference. I will admit I was completely wrong! This xHP app has transformed my 435i and has awaken my Stage 2+ ecu tune. This is a must need for any BMW. I kick myself for not getting this tune right away.
5 stars: Solved my 2-3 downshift roughness. Now not only all shifting is smooth but also fast. Best of both worlds. I really like it!
5 stars: #1 PERIOD for e9x series BMW's... I've never had a problem connecting, flashing, customizing, or Enjoying.
5 stars: This app is excellent and it performed flawlessly. It's very easy to understand and simple to use. As an IT professional, I wish all software worked this well, I highly recommend!
5 stars: So far so good. I was a bit confused and not knowing what to do but the app walks you through everything so, so far so good.
5 stars: Xhp is an awsome app. If you are going to tune your transmission, I highly recommend it.
5 stars: Awesome app, easy to use. Most importantly, the trans tune offered for the 6AT N54 cars is amazing. After flashing both drivability and performance make it feel like a whole new car.
5 stars: Completely change the way my car feels and performs for the better.
