Klemann K4 on C63
And when they say 580HP, from 0 to 100, how fast would a C go?
Those are really huge numbers! Pardon my ignorance, I'm new to all this.

I'm still waiting to try it . I will do side by side testing any day any time , If it shows more Gains then we will all know once and for all, If it does not then we"ll know Not to prove one is better but to see what the difference is.. but after seeing the hp gains me vs mhp on the dyno I would say my tune yields higher rwhp but the mhp tuning has the TQ managment down along with the TCU files and nice track #'s. So it's not always the higher dyno #'s but what you can do to get down the track. I'm always ready to test as you all know. I have the most modded CLS63 so the car is the best test for testing the ECU files. I will be hitting the track soon to try out my new setup and report back.
