2013 E63 Dyno
So today I decided to go to Original Autosport in Van Nuys, Ca to dyno the car, Dynojet. I have to say I am a bit disappointed with the numbers I did 2 runs. Dyno showed what I was expecting. The car noticeable drops off after 5k rpms when I drive it and it did show just that on the dyno.1st run 545 rwhp and 560 rwtq not sure on the tq rating. Car when warmed up a bit highest run is 552 rwhp and 615 rwtq, only did 2 runs. This was dynoed in 4th gear 91oct. I talked to Matt at HD he says its normal to fall flat like that top end. I don't know what it would've pulled in 5th gear but I doubt it would be much higher then the 552. All I have is Tune, High Flow Filters and Res Delete. The video is the 1st run I had to datalog the second run to send to Matt needed my phones dashcommand to do that so no vid of second run.

I know you don’t wanna take the cats off but they are fairly restrictive and I’m sure you’ll see good gains if replaced with down pipes. But if you can’t then it is what it is.
Also are you having heat soaking issues? What year is yours? If it’s none S maybe it’s time to split the coolant lines.

If they are not split, it’s something I highly recommend fling soon. (You can check to see if you have a reservoir next to your ECU).

This is the only other vid I have. He switches from mph to rpms. I also just did quick screen shot.
Those numbers seem fairly normal for an m157 tune, especially the high rpm whp. Forget about the massive torque that Peter and some others are showing. If you want that, you just have to have the tuner jack up the boost. I think it's largely pointless though since how often are you going to be basically full throttle at 2500-3500rpm without the car downshifting? It seems mainly for bragging rights.
You do have some little dips in the red curve which are kind of weird and may be creating that sense of power drop-off beyond what is normal. Those may be something for the tuner to work out. The blue curve looks smoother although it has lower values.

So the red version is at about 550whp from 4750-5250, dropping to 525whp thereafter. You are also showing SAE, whereas many tuners (like AMS for Peter) often show the higher STD correction factor. STD correction is about 3%-4% higher, so that would put you at about 570whp from 4750-5250, dropping to 545whp thereafter.

I dynoed it in 4th does that effect it much as well? Thank you for the help and advice

one car at a time
You cannot compare one dyno with another....the only thing you can do is log a 0-60 or 1/4 mile and see how your car performs....or of course log on the dyno before and after the tune....

+1. A dyno graph is only useful to show relative change if performed under identical or near identical conditions. Dyno graphs from different cars on different dynos under different conditions are completely useless. Absolute numbers on a dyno are also absolutely useless.

0-60 & 1/4 mile are also dependent on traction & DA ... again, there are correction factors
