C63 AMG
Here is my graph from the 5th gear pull and also the pull from the SL63 that I got the guy to print off for me.
Please let me know your thoughts. Im going to a different dyno and bringing my stock ECU in the next few days.
Thanks guys

To many things...
I have seen these lower power numbers before as well.....
Here is the results of a BONE stock C63
334rwhp and 344tq SAE

(Sorry the car is dirty it was snowing outside)
Here is a BONE stock C55 with only the 2nd cats removed, and res.
310rwhp and 340tq again SAE

(the blue dyno was before the cats were removed)
I am going to dyno another C63 soon, to see if the same thing happens. But I was honestly really let down in the power difference between the C55 and the C63. I mean really 24hp and 4tq difference between these two cars?

Your lines look smooth, and your AFR is actually very safe. I'm not sure why your readings came out to be so low. Could it simply be a dyno that reads very low? Especially considering the numbers that the SL63 put down... If you're feeling the power on the street or when you drive, then it may just be that the particular dyno you were on reads lower than others.
Also, not having a good fan (or fans) blowing cool air into the radiator and intake, as well as not having a good opening behind the car to get rid of the exhaust fumes can hurt your power numbers, too. That's all I can think of. Sorry.

Was hoping to see something more obvious.

SL63's, for whatever reason, are known to produce low output figures on the dyno.

Tuned C63's typically don't suffer that same fate. Either way, both cars look to be producing too-low of results; but the Renntech-tuned C63 more so. Good luck with troubleshooting your issue.
