Have a 95 C1500 that has a tired old 305 in it, going to be putting a Vortec 350 out of a 97 into it mated to the NV3500. For now everything will stay basically stock, stock exhaust manifolds (for now), stock cam, unbored throttle body. The only modifications will be the Jegs Intake Manifold, Holley TBI Adapter, and Vortec fuel pump. I also have an 18psi Spring in the throttle body as well as the typical pod spacer and Hypertech Bowl. I originally was going to go with TBIChips, but after reading numerous complaints, and reading more in depth articles on this site, I decided not to. My question is; what is the most cost effective way to tune this setup, should I attempt to do it myself, or should I find a dyno in my state (AZ) that has experience tuning this trucks? It will be a daily driver so I want to make sure it runs as close to 100% as possible.

I appreciate any help and feedback.
