294.7 * 1.25 = 368.375 torque --------vs. stock---------- 252 * 1.25 = 315 torque
And that's not even counting the low numbers for the Mustang dyno.
If you factor in the extra 12% for the Mustang dyno loss/low numbers you get
264.9 * 1.470588 = 389.5588 HP ------------vs. stock----------- 249 * 1.470588 = 366.1765 HP
294.7 * 1.470588 = 433.3824 torque --------vs. stock---------- 252 * 1.470588 = 370.5882 torque
So it looks like you aren't getting that bad of numbers after all.
I talked to RENNtech about the results and they said for that machine they were pretty good #'s (266rwhp). They said the stock C32 AMG on that dyno jet was 289rwhp.They also said on a dyno jet I would have probably been in the mid 300's.
[above edited, looked at notes and had posted wrong machine & #'s forC32 AMG- posted from home, notes at work]

A/F ratio's were the main reason for doing the dyno + I did want to know what it was putting to the ground. I was just so shocked because the rwhp was 80 or so less than what I thought I'd see.
