CamQuest VS Dyno?

Wasn't sure which forum this should go in so, if the mods want to move it, that's fine with me.

I was wondering if anybody had any real world experience to show how close (or how far off) CamQuest is with its predictions. Has anybody here run their combo through CamQuest & then actually put it on a dyno to see what it made & then compared the numbers?

I'm asking because I've been playing with my 408 stroker combo in CamQuest & it's giving me 647 HP @ 6500 & 594 ftlb @ 5000. I'd be plenty happy with those numbers but I don't think they're gonna' happen. [-( I'm just wondering if anybody has a ballpark percentage of HOW optimistic they might be. Are they high by 10%? 20%? More? I really don't know. :dontknow:

How HAPPY is the CamQuest dyno? :toothy7:
