Stock I dyno'd around 380 hp and torque. With only the K&N, custom 3" (cat's removed), dual borla xr-1's w/ crossover at first bend, vec2, and 180 tstat, I've consistently dyno'd at 455 HP and 505 torque at the rear wheels. Only 6500 miles on it, with over 13 dyno runs. I dyno'd after every mod individually at the same dyno shop. As I recall I picked up about 70+ HP and 122 lb/ft of torque from just the vec2 aggressive card. I initially lost a little torque from removal of cat's and 3" exhaust (when this large in anticipation of roe racing's blower), but more than compensated for it due to their tuning. Despite a loss of torque due to backpressure (before the vec2 install), consistency was greatly improved due to the improved heat dissipation. Runs much cooler now.
Roe Racing's VEC2 was the best money spent on the truck, including swapping out to 4.56's. Vec2 is going on my quad cab srt-10 as soon as I have a chance to get back up there.
