2012 C63 Coupe P31
Dyno today 12/15/18 - 2012 Mercedes C63 P31 - 450.42whp and 401.29 ft-lbs SAE Corr
Hey guys just posted this over in the HP Tuners forum,
Hit the dyno today and was able to get 450.42whp and 401.29 ft-lbs SAE Corrected on a Dynojet 224x dyno!! Uncorrected values were 449whp and 400 ft-lbs. Weather was in the mid 60's here in central FL. Run 3 was my baseline on Jan'16 with AFE Power air filters and ROW airboxes and Run 17 was my HP Tuners street tune where I ran 11.844 @ 119.4mph (Michelin PS4's) and the mods below.
Car:
2012 Mercedes C63 P31 coupe with LSD
Mods are the following:
AFE Power Dry air filters
ROW airboxes
MBH Motorsports headers
Quaalude's midpipes with Magnaflow 59959 cats and Vibrant 17695 race mufflers
MBH X-pipe
stock resonator
stock exhaust
Quaalude's custom HP Tuners V1 tune
I'm finally able to say "money well spent" on the above mods because I gained 62.74whp and 51.94 ft-lbs over stock and bet my best stock time of 11.96 @ 117mph (Goodyear street tires) with my HP Tuners street tune. With MBH headers and EC tune, I was never able to get into the 11's (12.06 @ 116mph best). I gained 25whp and 21 ft-lbs from adjusting A/F's, adding in timing, and VVT adjustment. I should be in the mid to low 11's with 122-123mph traps.
Thanks BackyardTurbo for some of your tips and previous posts and HP Tuners for an awesome product!
Here are some dyno run vids:
My M156 street and dyno tuning services are available for the greater Tampabay area or remote tuning with HP Tuners lol.

Nice! So 11.84@119 was with headers and your new tune? I have headers and EC v6 tune and it took 100 octane to get me to 11.91@117.5.

Yup, 12.06 @ 116mph was my best with EC V7 and previous listed mods except catless mids (currently selling in marketplace 😉.

How much timing are you running from 6k and up
I made 405rwt and 460whp with almost the same mods as you.
It looks like we have a Dyno that is very close as mine as I am trapping 119 to 120 depending on conditions and fuel

Yes, I noticed the power you were putting down with almost the same mods but with OE Tuning tune. Your traps are really good and I was hoping to trap in the same ballpark with my EC tune and MBH headers but no dice. Recently, I just trapped 119mph with 424whp so with 450whp on the new tune, hopefully I should be hitting 122mph in 1/4 mile.

Check out my custom wideband A/F gauge mount to verify the lambda (A/F ratio) measurements for tuning. AC vent is fully function except air flow is slightly blocked by the gauge lol. Even though Mercedes uses stock Bosch wideband O2 sensors, it's always good idea to verify that the recorded lambda data matches against a known calibrated wideband O2 sensor. Plus, the sampling rate on the AEM gauge is 100Hz, which is really fast, and good for tuning A/F's.

I went back to the track again on 1/17 and 1/31 when the weather was cool here in FL. My car is running consistent 11.8's on Michelin PS4 at stock tire pressure, full weight, and 93 octane. These runs were done with about 1/2 tank of gas. Runs on 1/17 I ran 1 degree less timing than my dyno tune and dyno tune timing on 1/31 runs. Second run on 1/31, the ecu was pulling timing as I was getting some knock, hence the slower time and lower mph. I finally went over the 120mph mark with my best time ever of 11.806 @ 120.43mph. I think she can go a little bit faster with more practice but without spending a lot more $$$ on next set of mods (i.e. TB's, nitrous, supercharger, drag radials), she is pretty much tapped out. I'm really happy with the HP Tuners product and recommend it to anyone wanting to datalog their car's parameters or tune their car , or have me tune it.

Nice numbers !
I just got dyno tuned using hp tuners a couple weeks ago and put down 452wheel and 409tq. Only secondary cat delete and resonator delete using 94 octane.
