Being new to the C63 i haven't seen many direct before and after numbers when it comes to tunes here on the forums. I also wanted to contribute some information to this forum that has given me so much knowledge when I purchased my car.
Dyno was done at European Auto Source in Anaheim CA on a Dynojet.
Car is a 2009 C63 with 102K miles on it.
Only mods are Weistec ROW boxes and Weistec dry filters. 91 octane fuel was used
Highest baseline was 383 Hp 375 tq
Then loaded the tune and did a few non charted pulls for the ECU to adapt and then got the following 430hp 391 tq.

Nice! That's about what I made. 380 whp and then 426 whp. I wonder what v5 vs v6 would make. They claim 5-10 more hp but you can see that much from the first to the last pull.
Looks like HP and T both fell out at 7,000 rpm, so I'm guessing that the test was run with the transmission in C mode. Would HP have gone higher if the engine was allowed to run to 7,200 prm redline?

I'm not sure actually, all i know was the dyno operator said he put the car in "dyno mode"?

How would you do it in C mode? The car would just kick down (ask me how I know). Even in dyno mode, M mode is needed to hold 4th. Maybe they just didn't rev it all the way out or theres a slight RPM reading error.
