If you want the power you will need to install a quality exhaust. I have yet to see a quality aftermarket cobra exhaust so I had one built. You also want to look at the air filter assy. Lots to lose there.

I suppose I'm a little biased as we custom assemble our own Quick Fuel carbs. Never tried a Pro Systems, but have heard good things about them. I have sent Quick Fuel carbs all over the world (literally) and have some good reviews from my customers. The carbs that come with the Roush engines are pretty sub-par...
As far as the dyno, a 25% loss through the driveline and exhaust isn't abnormal with the Mustang dynos.

Could you share some thoughts as to the gains seen with the suggested carbs, realizing there are likely lots of apples to oranges type issues. Still it made me curious.

I really don't know why the Street Avengers are turds...possibly because they are just smaller, vacuum secondary carbs, with minor adjustability.
The Q-series Quick Fuel carbs are mechanical secondary carbs, with no chokes or choke horns, and are pretty much infinitely adjustable.
