He has posted a link to his dyno sheet ... go back and read
Nice numbers

Sheet or not, I don't see how that much boost on pump gas with 550cc injectors and running timing and A/F ratios that are not completely insane can make ~400whp.
There is something that just doesn't add up here.

Facts?
Dude, you haven't even posted a dyno sheet?!
At this point, you are asking us to take your word for it and providing nothing else. Several of us here are questioning the results that you posted with very little proof because we find them hard to believe based on our own experiences.

It's blurry and zoomed out but you can see he made just under 400hp and the AFR look pretty steady under the 13 line.
I'm still in disbelief over this but short of going to dyno's around the country, what else do you want him to post? He's posted vid's of the pulls, two dyno sheets, and pics. Personally, I'd like to see him dyno on a different Dynojet.
James, the reason everyone is bugeyed over this is because there are is a direct relationship between the HP a motor will produce under the best conditions, and the fuel and air required to produce that power. I am not saying that EVERY F20C (or F22C) with identical modifications and an injector duty cycle of 95% will produce identical HP...there are too many other factors. BUT, assuming both motors have similar compression and are dyno'd under similar conditions, the HP number should be pretty close.
Either your car has been touched by the hand of God or something isn't quite right. Dyno'ing on a different dyno @ 7psi would shut everyone's pie hole. Make sure to document the pull with video of boost level if you do this.
'course...you could go about you merry way and shrug everyone off but I think it would really benefit the community if you didn't. Personally, I'm rooting for you cuz I'd consider your identical setup if this is the case (it's low enough boost that I should be able to track the car without too many problems).

Actually, he did link us to this:

Was there correction added to the plot? Why no TQ curve?
That plot posted above looks like an AP1 vs AP2 HP plot. Notice how one is around 1000rmp lower than the other. Of course it's in MPH but that's about 1000rpm. Of course it could be a starting tune and ending tune, as the AF on the red line looked as if it was leaning out near the top, I would have shut down too if I where tuning the car.
I agree that there is no way 550cc injectors will make that power. You would be way lean. And that's math, you can't argue it.

Look at that A/F! In the 12's and then finally gets somewhat safe at the top. Can you say Ka Boom soon? Not sure if that guy tuning knows what he is doing. I bet he is running stock timing too. LMAO

Do you guys think the power he got could be higher because of the gear that they did the pull on? In the one video it looks like they did it in 4th gear and then in the other video (unless he started recording late) looks like it was 3rd gear. Just a thought.
