'11 C63 w/ P31
C63 w/ P31 OE Tuned! Dyno w/ Video!
Warning: This dyno is a very low reading dyno. Most C63's with the P31 package dyno around 420whp stock on a dyno jet.
Stock the car ranged from 378-394whp
Tuned it ranged from 417-427whp
So that is a gain of 33whp and 32trq. Solid Numbers. I wasnt expecting these results at all as I have heard you couldn't gain much out of a tune on the P31. So thanks to Jeremy at OE Tuning!
The 1 funny thing is that I raced member Xtyper in a video you recently saw posted and when he was tuned and I was stock we were tied every time, was dead even. Xtpyer dyno'd at 420-422whp on the same dyno that I dyno'd at 390whp stock. So weird that we were tied racing but that I dyno'd 30whp less.
So to get some more real world results, we will have to get back out there and do some runs again! I also will be using the Vbox again, and try and beat my old time, which was pretty solid and I havent seen beaten by a tune only car yet.
Also to note. I took out my charcoal filters after and did some more runs and there was no gain. Did 3 runs and they all were in between my highest and lowest dyno. So I can say there was no dyno gains for me. Maybe at driving speeds it helps.
Video of Tuned Dynos - these pulls are actually without the charcoals, the highest run which you can see the dyno line in the vid had the charcoals in, but there were also runs with the charcoals in, that were lower. So I dont think it made any difference on the dyno

I'm confused by the data vs. xtyper's car?
So, you were running (stock p31)neck and neck vs. xtyper's car with 30+hp?
Was there any weight differences between the two of you guys? (eg: passengers, no spare, less fuel, just skinnier?)
forged internals?
And as suspected the tuned p31 only gains about 5hp over tuned non-p31.
Great data, maybe we'll get a clearer picture with more Vbox data.
Thanks for being the ginny-pig
Nice to know there is some room left in my car if I decide the p31 is not enough, but I'll wait until my warranty is up first
Nice work

Real world results needed for sure. Very odd data coming from the P31. That chart looks like a stock non P31 vs a tuned C63. Is this the standard tune from Jeremy? Any race fuel added?
If that dyno reads as low as you say then that tune brought the P31 to almost 450whp tune only?

No race fuel. I had about a 1/4 tank left of 91 octane.

I've asked this question before but no answer. If P31's can be tuned to make more power, than why can't all C63's be tuned to make as much power as a P31 that is tuned?
They are the same cars, no? Doesn't it all come down to maps in the ECU?
The octane is the same--91 octane.

Remeber the thousands of variables that go into dyno's temps humidity strap tightnes.. Not to say the tires on the car the p31 also comes with lighter breaks and lighter motor internals that would equate to more hp..

Any difference in the version of the tune? Or is it the same tune used on the non P31's?

I understand the different environmental factors that can affect a dyno run. I'm just asking if this tune is more aggressive than nonP31 OE tune? Is there more on the table for regular C63 tunes on 91 octane? I just think its an interesting topic, that's all.

OE Tuning C63 AMG
I totally agree that this should be tested again in the real world post tuning (vbox, comparo, etc). The results were great and definitely dispell any truth to "no more power can be made through tuning", myths and beliefs. I have attached a dyno that compares a Regular C63 (xtyper) vs P31 C63 (DD GT3 RD), baseline vs ECU tune, running CA91 pump gas. What can be noted is the lowend Torque of the P31 is stronger tuned and untuned, attributed to light weight internal components (a personal theory). The "top end" is also what is expected of the P31 package. Less limitations to throttle mapping from AMG give the added power up top.

Putting aside the theories on lighter weight internals for a moment, couldn't a tuner reduce the throttle limitations on the non-P31 C63's ECU to the same extent as can be found in the P31's ECU?
Or is the mapping just so different that it's like comparing apples and oranges?
Edit: Looking at the dyno results it seems from that form of data that the P31 stock tune is a completely different animal from an OE tuned C63 and perhaps it really is an apples to oranges comparison. Still seems odd considering the engines are the same, aside from the forged internals. Congrats Jeremy on making further progress with the C63 and now the P31.

I was thinking maybe it would be a cool idea to learn whether the forged internals of the P31 do help produce power over the regular M156 internals.
One idea I have is to compare the spark advance in certain parts of the stock P31 tune to those same parts in an E or SL63. I know the E has different size diameter exhaust piping than the C63, but I'm not sure about the SL. Maybe that's 2.5" as well.
If you could identify what the spark advance is in certain tables in the stock P31 tune and compare that to similar tables in the E or SL63, and then you compare that to the respective throttle blade openings, and finally, the respective rwhp/rwtq output from the engines, you could hopefully determine whether the forged internals are making extra power.
I apologize for my lack of sophistication in these matters. But, I am trying my best to articulate my curiosity.
