Looks like it ran a 12.5, isn't that pretty much what stock x6m runs? Unless there was alot of wheelspin, I question the 720hp, should have been low 11s

Without seeing the 60 ft and reaction times it’s hard to say if the 12.5 quarter mile is just down to a bad driver. Or the tuner is full of crap or both.. oh wait this car has launch control..... so probably making about stock power levels...
Anyway I’ve learned the 2 biggest liars in the auto industry are diesel owners reported fuel economy and tuners power outputs. A lot of tuners claim ridiculous crank power correction factors like 20% or more. It’s what the car can due on the strip and in the dyno uncorrected you should pay attention to. When lots of corrections are added it’s more about engineering a number the tuner wants than achieving it. |
