Tfs 220 & vrx5 ls1 purchased heads and cam package from Vengeance Racing to take advantage of the Labor Day Sale savings. Had my buddy Tally Trans Am install everything and tune it at SS Performance Group on their AWD Mustang Dyno. Im very happy with how everything played out and the results that were netted 445/409. Here's the graph.
Still on LS6 intake, stock fuel pump and injectors, restricitve y pipe. These will all be upgraded soon.

Looks good. I wish I would have had the cash to take advantage of that deal. By the way, what's the specs on that cam? It's pretty big isn't it?
I bet if you upgraded injectors and went with a true dual setup, you'd be pushing 465+rwhp.

Yes stock LS6, stock fuel pump and injectors. Injectors were logged at 98% duty cycle up top. Gonna try to cure that with a good fuel pump first.
With those Mickeys it dead hooks at a 4500 clutch dump on the street with no burnout. It made my stomach drop and it felt like a rocket ship. Way way stronger than my previous set up. Driveability is awesome for a cam this size, no bucking or surging at rpms above 1500. Just gotta fine tune it for coming back to idle.

well i guess now i have a pretty good idea what im putting down...what prob you having with coming back to idle? took me and my tuner like 3 days after work to get it to return to idle and start up right...
on a few cars I know personally that have been on dynojets as well as our dyno we have seen a roughly 5% difference on cars making approx 450-600 rwhp. don't have a good comparison on lower or higher power cars
the tune isn't quite finished yet, particularly at idle as it hunts more than I would like, but I am hoping to get a little more out of WOT as well. I'd love to see what it does with a ported fast 102 and good exhaust.
