Article: MRC Tuning C63 AMG M156 V8 ECU remap - +67 horsepower

[Sticky]

UK tuner MRC Tuning is tackling a variety of platforms these days. Known mostly for their VW Group work (Audi, Porsche, VW, Skoda, Lamborghini, etc.) they are branching out into the Mercedes market as well. Their ECU tuner offers a gain of 67 horsepower over stock. The dyno provided is from a Cartec dynamometer which was set to read the crank values. We would have preferred to see the numbers at the wheels and at the crank including the losses as with their R8 V10 dynograph but at least they provided a graph unlike most European tuners.

No pricing, fuel, or export information was included which is disappointing. However, we are sure the M156 scene welcomes more options.
