Hey guys i just got my 2001 c5 tuned on the dyno last night(finally), and i honestly expected to making more power. my mods are TSP TV2 cam, Long tube headers, Flip tie mod, and 3400 stall by PTC. are these numbers on par? or is it low.

I think you made the power the cam advertised. Since you're an auto car you're losing at least 15% if not more through the drivetrain and that graph is wheel horsepower not crank horsepower. My C5 made 321whp 10 years ago with only intake and exhaust mods and it is a manual so 380'ish sounds about right to me as that is a 60whp gain on my old number. Like I mentioned you can calculate the drivetrain losses and extrapolate to see what your crank hp would be if you were basing your expectations on a baseline of 350hp Chevy advertised.
Low dyno numbers?
looks spot on with the mods you listed.
