Hi,
My on-wheels dyno at Uber Garage indicated that the chip produced 140.9bhp and 251Nm torque "on wheels". Do note that BMW specs indicated on the brochure is "on crank" which would yield a higher set of numbers.
You may wish to refer to the link below for a rough guesstimate on conversion between "on wheels" and "on crank" horsepower.

The only items I modded are high-flow drop in air filter and Bastuck cat-back exhos.
I can send you my dyno chart via whatapps if you wish. Thks.
