TuneTime: Judging by the big logo in the left corner, it is DynoDynamics chassis dyno.
335 at the wheels is very low, it should be in 370-380 range.
419 estimate that operator created, implies that there is 335/419 = 20% loss at the wheels which is not true either.
Find a Dynojet and use it. You will not have to worry about operator creating fake numbers.

DynoDynamics dyno is a very good tool in very competent hands. However, most of the time operator does not properly sets or manipulates vehicle dynamics data - resulting in wrong numbers. Either too high or too low.
Dynojet, on other hand, has a fixed load and thus gives very consistent numbers. Even from dyno to dyno.

True the Dynojet gives good consistency and repeatable results. I however found the best tuning by using a Mustang Dyno, where the rollers use magnetic eddy currents to simulate road resistance, wind etc.
But enough of that, just post the new RennTec ECU flash numbers already!!!!

You need to baseline your C63 on a Dynojet. They are extremely consistent dynos which is what you need to supply the MB community with accurate information. My C63 baselined at 380 rwhp which is what it feels like. Ill send my PCM to Vadim once he has done one with results. I'll post the after results as I can get my car back on the same Dynojet quickly.

It's the same engine that makes 518 hp in other cars, I doubt they do this by restricting the intake and exhaust, it's probably mostly done with the comptuer.... BMW can take away 100HP with the computer on the M5 with the push of a button by the driver, I'm sure MB can restrict power as well this way..... I hope so, 500+HP C63's will be fun and king of the MB performance #'s until the AMG V8 twin-turbo arrives!
What kind of results are you expecting. ECU tunes on a naturally aspirated car are not all that impressive. Usually the tune just leans out the A/F ratio to extra a little more power but that is not the best thing to do for the motor. With other changes, headers, airbox, etc, retuning does make sense.
