X5 M50i DYNOTUNE! 536hp/826nM to 690hp/928nM Pics & Vids

First things first..... the numbers. I am in Europe, so everything is measured in "metric" hp, and Neuton meters of torque. So I'll do the translation to US numbers as well.

Baseline dyno -536 hp / 826nM
US measurements - 529hp / 609 ft lb

After remap - 690 hp - 928nM
US measurements - 680hp / 685 ft lb

(EDIT) DISCLAIMER:
Numbers are in crank hp, just like the manufacturer advertises, and just like most modern tuners advertise as well. However, 690 "crank" hp equates to about 570 "wheel" hp. For those that are interested, that is about a 22% increase in performance on an otherwise stock vehicle. (Sorry.... I got trolled later in the thread, so I had to add this)

Secondly..... gotta give a HUGE shout to BR-Performance in Willobroek, Belgium. These guys were amazing. Walked me through the whole process, explained everything, step by step, even gave me a free shirt when I asked.

And.... when I inquired about adjusting the sport gauges to reflect the "new" horsepower levels..... they brought in a guy to do it..... no charge whatsoever. Turns out, at least as of "right now", they are not able to increase the hp levels on the OEM gauge over 640. Not sure why.... but I "assume" that is what the new X5Ms read perhaps? Hey.... I'll take it. Reading 640 is better that reading 550 from the factory. When I hammer it though..... it PINS the gauge at 640 and keeps pulling.

I hate when people "describe" what it feels like in words.... because it's pointless and subjective. I will say..... it was a beast before with 529hp. How do you think it feels with 151 more hp? It's insane. Absolutely insane.

But.... under "normal" driving..... it feels 100% stock. Sounds right, drives right, shifts right. My wife could drive my car, and she wouldn't notice any difference in how it drives..... unless she put her foot on the floor. Guys did a truly amazing job of tuning it.
