They are not the best at throttle response because of the huge plenum, a much smaller plenum would probably make them "feel" more TQ but not actually show up on a dyno. Also if the thing gives it an extra 10-20 pounds of TQ VS say a carb intake it will be hard to notice in the seat of the pants. Also if your truck is an auto it just wastes the TQ down low because the converter stall is too high. Even if it does that you still have very hot air so the air that is rammed into the cylinder is hot and not very dense so some of the effect is lost there. I have installed the Hughes airgap intake and it noticably loses TQ in the very low ranges and shifts it up higher, I would take the kegger any day in a real work truck and I bet if you could truly get rid of all that heat then it will really shine.
