This just in,
it seems like Mat Watson from Carwow got ahold of two xDrive M3's, one of which was stock (yellow) and the other being tuned (black).
The tuned car was otherwise stock and had a stage 1 ECU tune by Wrench Studios, giving it an extra 90hp & 73lb-ft of torque.
The stock M3 did the 1/4 mile in 11.2 seconds while the tuned car did it in 10.7 seconds. Both cars were on OEM wheels/tires.
I'm not sure if the stock car is ready for the stage 2 map?
Maybe it needs catless downpipes or high-flow cats but the stage 1 tune could also be a great option for minimizing stress to the engine, although I'd assume the engine could handle the stage 2 map on the stock setup as well. I'd appreciate it if anyone could give me any feedback on that.
Enjoy
