Finally got back to the dyno...
I dyno'd my stock 2010 C63 P31(performance package) last September on a Mustang dyno & finally got back to do some more pulls after I did a few mods during the winter...
Eurocharged V4 tune
ROW air boxes with AFE pro dry S filters
Replaced secondary cats with an x-pipe
Best 2 stock runs:
380/382whp & 353/353tq
Best 2 modded runs:
407/409whp & 375/375tq
All runs were done in 4th gear
Mustang dyno inputs:
HP@50 = 11
vehicle weight = 3875
As for the end rpm showing 6800, it was just the rpm calibration being off at redline, I did run it to 7200
Results are kind of what I expected, was hoping for a little more, but I know these tunes don't give much on P31 cars.

Yeah that is good result for mustang Dyno.
So basically the tune gave you around 20whp from stock. I think that is the average gain for a P31.

Those are impressive numbers. Just wondering though, do you think a '12 and up with the MCT and the P31/LS would fare better stock and with the tune? And are these tunes legal for smog check purposes (I'm in So. CA)? I am very new to the C63 having purchased mine in April of this year.
