Having had 4 months with the OpenFlash Stage 1.2 on the car I decided to arrange a Dyno Day the see how much the Stage 1 map was producing.

I run the car on 99 Octane fuel (93 USA equivalent) and it has no other mods. The car is a 2016 M5 Competition Pack with 11,800 miles covered.

The performance is impressive over stock the only issue being traction at this time of the year.

The car achieved 708bhp and 628ft/lbs at the crank.

There was another M5 that attended with a Bootmod3 Stage 2 (reduced torque) catless downpipes, straight through exhaust and venturi intakes. This produced 734bhp and 642ft/lbs. It sounded like a beast compared to my car.

Really looking forward to receiving the OFT Stage V2 and comparing that to the V1.2
