Looking for a dyno sheet 5.3 stock, 5.3 with procharger

I want to do some comparing on a vehicle I just tuned. Does anyone have a stock 5.3 truck dyno and a procharged 5.3 truck dyno sheet preferrably stock maybe with headers.

No dyno sheets but should go from roughly 250whp to 420whp with about 7-8psi. That would be through a 60e.

That sounds about right, I did a 112 maggie on one the other day that did 383 unlocked with all stock exhaust @8-9psi. Remember you are only starting with 250whp.

I stock 07 5.3 is around 236rwhp/237tq. A 07 5.3 with 8.5psi p1sc with long tubes and no cats 3" exhaust is about 438rwhp/406tq and still climbing but stopped pull at 6000 because still on stock springs.
