Dyno Numbers
hey guys
Did my first dyno ever today and this is what they gave me. do these numbers look right to you guys? 2012 coupe performance package i have a ECU tune and akrapovic cat back.

Your numbers look fine....but one can get those exact same numbers with either a tune or the p31 package. Now the question is, what exactly did you gain from tuning your p31 car?

See Sig
That is a low for an uncorrected Dyno on a Dynojet. If that was a mustang dyno fine. I would do a few more pulls for a good baseline number.

This is very low. Which tune do you have?
By the way....your smoothing is set to 4
and it is uncorrected
if it was SAE corrected and a smoothing of 5 your numbers would be even lower.
Sorry, but you have a bad tune. A stock P31 should without a tune dynos better than your car
one more thing. what is the factor used on this dyno?

I just read your dyno conditions. Humidity is @ 42% temperature is @ 79F with a correction factor of 1.00.
I swear to god if that was my car I would be smacking my head on the wall and have my tuner answer some serious questions

im going to assume that the guys who did it didn't know what they were doing. ill take the car to another place with the same dyno and compare numbers. will try to get it done in the next day or two.
Thanks 7aboob min thokik. Good luck in school buddy ow when your back home shoot me a massage and ill be more then happy to take you on a ride.

What is the temp where you are?? Sometimnes the dyno temp and humidity aren't correct.
You also have to remember that you are running a header tune without the headers so its very rich and the numbers will come up once the headers are installed. Hang in there and be patient. You'll have the power soon enough.

The numbers look quite low to me given your mods and being uncorrected on a dynojet in those conditions. I would have expected something closer to 440whp.
Also, not sure I agree with Keith about the header tune causing it to run rich since your AFR curve looks spot on tapering to 12.0 at redline. I suppose you might want to go 0.5 points leaner, but I doubt that would close all of the gap.

Man you are running a LT header tune without the headers?? lol
Why would you even dyno the car???
I am going to get a Weistec super charger tune with no blower then dyno my car and wonder why the numbers are low... Really??
Dyno's are only good for comparing mods on the same day... Go to the track...
I ran my car on a Dyno with a Renntech 510hp tune and I got 363HP....That's 442 Crank HP.. Thats what the car is stock.. So IF I listened to a guy like Jacob, Id be smashing my head into the wall and *****ing at my tuner for no reason.. Because the next day I went to the track and run 119mph... up 4-5mph from my best stock time and right on par with a 4000lbs car running about 500hp.

why would anyone dyno a car? i ran a dyno personally for one reason to have a base point of where the car is. plus headers tune or not i should see some bigger numbers over stock. im not here to argue if the tune is good or bad i just want to know what could be the reasons behind it.

If you baselined your car, then you should be comparing your tuned dyno runfile against your baseline dyno. The dyno runfile you posted up is about the HP numbers a stock p31 car will post up. If you had performed the baseline, you would know immediately, whether or not the tune did anything for your car.

The reason behind it if you read and listened to my post is dynos suck and take your car to the track. My dyno numbers blow, but my track numbers were spot on.. Reasoning behind it?? Who knows.
I know that they dynoed a SL63 and he was 2hp higher than me.. So we are both putting out the same hp and a SL63 is rated for 510hp ish.. So my tune was bang on and the guys dyno is not calibrated right.

Well, I guess you did not need my advice and you already switched to OEtuning.
and by the way, Which dyno were you making your runs on? (seems a dynamics dynomometer to me)
I'm just saying I know about dynojets a bit. and with his factors and conditions the numbers are low. Any person who understands the dynamics of a dynojet would agree with me.
Good luck.

even with the header tune. The ECU will adjust itself to the necessary ignition and eliminate knocking. NO Problem! I had that issue once.

I never ran a MHP tune before. Just renntech and now OE header file. There was too many things going on with MHP when I got the tune so I just went with OE... Otherwise I probably would have tried his tune as its been working good for other guys.
I don't care who's behind the product as long as it performs like advertised.

Not sure what Dyno it was... But like this guy I was choked at first. Then after a trip to the track, it all made sense...

Oh and by the way, When yoiu said that an SL63 made 2hp more than you did, I can say that there was something wrong with your tune.
The SL63's are known to dyno less than C63's runing with the same crank number due the MCT transmission wet clutch sucking up more horsepower.
The drivetrain loss on the MCT is more than that of a dual clutch at about %5-6
The SL63 US spec is rated @ 518 HP.
I understand the OP also has the same MCT transmission. Still his numbers are low for the factors and conditions given. My SL63 dynoed 465rwhp on more conservative conditions when it was naturally aspirated, I was runinin with an SAE correction and a smoothing of 5, check it out (by the way look at how small the fan in front of my car is):

Thats is correct. The best thing to do is to dyno the car before and after a single mod to see if the gains are intact. When someone comes up and posts a dyno graph of a tuned P31 2012 C63 on a dynojet uncorrected and a smoothing of 4 making 410HP, I seriously think something is wrong.

This is the difference between a real tune......and a BS tune

So stock vs stock SL63 makes less rwhp then c63?
