How come you don't ask other tuners questions like this in the same manner?

XFT have made 430rwkw with room still on P100 so its a 400rwkw anywhere else no worries.

Have you looked carefully at the XFT dyno graphs though? He's winding some of them up to around 6,800rpm to hit 400rwkw in the Miami's on pump 98. If everywhere else is keeping to stock rev limit then they're on par if you back calculate the power XFT are making to the stock rev limit.

RPM has nothing to do with what power its making and the claims from some 400 is not possible on a stock fuel system.

Fuel was still flowing in the return to tank(XFT confirmed this),AFR is fine and the car makes 430rwkw....make of it what you will.

So because I have no experience with DynoWog I am not to have a opinion that his work is sh*t?

Maybe some tuners know more than other tuners hence the better results?

Could this at all be possible?

standard fuel system we have seen 396 I think it was, but no return line flow, the ramp rate was increased so more timing could be added to give an artificial power number, this was done as an experiment and the car ended up with 370ish final tune when loaded as we normally load them.

Our electronic knock detection equipment picks up engine knock earlier than the human ear will pick it up, if somebody was to use a "spotter" to listen for knock there is a good chance that they will get more power for the same load conditions though because of the extra timing
