It will only pick up that kind of HP and tq if there was something wrong with the setup. If it was deficient in some way.
Going from an A4 to an M6, if you're running the A4 locked, makes little difference.
Now, back to my original question, is it a 403? If it is, its pretty weak. Before or after the latest mods.
Now, if the compressions off, if theres a bottleneck thats causing a restriction at higher rpms, then theres your reason. Theres ways of diagnosing these problems too, but it needs to be in the hands of someone with that capability.

That is just internet racing, 460/450 is darn good on those cars. Nothing is being said about motor health, ambiant temps are hellish, tune looks shaky looking at it but dyno calibration is not the best in this part of the world.
I know, I live here.
Exemple 53* C today

edcmat-l1 Thanks a lot for the help and info man. 
You dont say
I dont think the heads is the problem they already made 445rwhp with A4 and crappy crappy boltons.
Thanks and yeah the wheather in the 2nd dyno runs was freakin hot.
I'm thinking about visting Dubai Soon maybe I can finally meet the famous PREDATOR

I had those heads and the original cam (almost) in my 383 and made 490/445rw. I agree with the other guys. Check the health of the motor. Something is not right. Get the tune square and see where you sit.

Here is the graph for both. When I ran the 10.8's@130 I was only at 478/435rw in the 383. The graph is from the dyno tuning session the next day. I found some power through tuning. Actually alot in the mid section. Reminder, the 416 had about 1,200 miles on it and still has the thick 20/50 dinasaur oil in it. I am also switching cams and going to a max effort Fast 92. It was also 87* and humid with no correction factor for the 416. So there is alot more in this engine. The 383 had exelent air. I think the 383 would have made much more power with a AFR 205 or TFS 215. The PRC LS6 head had a 240cc intake runner and not that great of flow number. Their new revised head seems much better.
