"It's sound like its a bit busy over there with all the other tuners. Probably not the marketing approach, we're looking for."

ECU Flash

  • OE Tuning $1195 - Although this is made for the C400 it has been confirmed that it will work for the c450 coming in at 448 hp and 533 torque these guys are boasting some of the biggest gains. Our review on this tune can be found here.

We also addressed the "dip" in the early torque band and horsepower dip at redline that is noticeable on even competitors tune(s).

Additional Performance Mods:

  • RENNtech Toe Link Kit for AMG Models $940 - Adding a RENNtech toe link kit maintains stability at high speed, ensures the vehicle tracks straight under heavy acceleration as well as properly positions the car's suspension under heavy cornering and braking loads.
  • Performance Air Filter $229 - BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.
