Performance for your ML63

Finally, a section for the twin turbo ML63.

If you have owned and have been tuning and testing an ML63 you know that the numbers that are advertised for the E63, CLS63 and S63 do not equate to anything on the ML63. This is the first tune that we know of that has been specifically designed for the ML63. We spend 3 days on the dyno fine tuning this tune and we will continue to develop the tune over time. We have already been back on the dyno again to modify some real world glitch that we experienced with the tune.

We installed a new dyno last week so we were messing around with it all weekend and we did some testing on some cars. One of the cars that we spent a lot of time testing on was a 2013 ML63 w/ performance package.

ALL TESTS WERE DONE WITH 91 OCTANE CALIFORNIA FUEL AND A HOT ENGINE. We also used a Mustang AWD linked dyno. Our goal is to do real world, worst case scenario tests, not the highest number fluff tests. We could easily get more power by running the car on better fuel and doing it when the car has cooled down but we want realistic numbers for this, not marketing numbers that you are used to seeing companies post.
