Silverado 100 Horsepower Performance gain on a budget

[Canucktrux]

We'll be doing a right up on a cam install very soon.
The exhaust after the headers was stock except a flowmaster, no cats.
The cam install time depends on the installer, but 4-5hours is typical.

How is this cam install write up coming? I'ts getting colder up here now, so the performance mods will be starting soon..lol

Allen,
How did you get that truck to hold the HP all the way up to 6500? I put down almost the same peak HP with 30 extra tourque but it drops major after 5800.. any ideas?

Max power was actually about 6200rpms, but we revved the engine to 6500rpms to see the full graph.
What kind of valve springs are you using?

Comp Doubles with titanium retainers.

here is my run it sounds good all the way to 6400 but the graph just drops around 5800.. You probably know me better By Bryan since you have done so many retunes for me (Thanks)

I know I have to setup my rev/? on my dyno to record the correct RPM, maybe the dyno ignition or sensor isn't calibrated. If I don't set mine up, actual rpm and dyno recorded rpm are about 600rpms off.

This would make perfect sense b/c the if the truck feel off like the dyno showed It would feel like I lost 3 cylinders.. I need to make it up to SA to have you fine tune mine on the Dyno.
