Did you replace the valvesprings? It sounds like power if falling off before peak if the HP numbers are lower than TQ, but the TQ numbers seems pretty close to what they should be. Thus, you might have a lot of valvetrain instability above 5500rpm.
Another thing, are you revving the engine to 6600 at least on the dyno?

The "hoe master" might be killing you a bit, but I wouldnt think it would be a huge difference. What was the AFR? How much timing is in the car? I would think with a ported TB, undrive pulley, cutout you would prolly gain a little more then 10 extra ponies.

I agree its not all in the tuning , the torque shows there is some restriction , i only asked because his location was D/FW ( same as mine ) and the 13.5 a/f seemed a little lean to me for the dyno , they lean out more on the street , myself and other tuners i know in the area set them up a little richer on the dyno for this reason ..
Just wondering where he went ..

Kinda thinking that but i didnt want to ask outright .... Your pushing the limits on those 918s .. where they pulling it up in the RPMs? does the graph start to taper down or is it pretty smooth all the way up ? Post up a graph , or come by the shop 1 day id like to take a look at it for ya ... Im in Benbrook if thats close to you swing by , or give me a call ...
