Regardless, from looking at some other stock dyno plots, it looks like they make about 350 WHP at 7500 RPM. Power seems to pretty much level off in that area of the curve. So like I said before, he didn't quite make it to peak power but it should be much closer and not 50-60 WHP low. I don't know what the gearing of the DCT is but he may have used the wrong gear which could produce this discrepancy.

There's just too many unknowns here. NOTHING about this dyno session is correct from what I can tell. I'd have it done again and consider these results garbage.
It should not be limited...I had the speed limiter removed. But havent REALLY checked to see if it is or not. Is this how the car reacts when it hits the limiter 150mph/250kph?
