Hi Guy's. Pardon the many questions, I appreciate your help. I want to do something other than a supercharger because they are so damn expensive. I'm thinking Cam's and Heads. What type of increase would I expect from doing these upgrades? What type of tune would I need to get? I'm on the west coast and would like only the best to work on my truck. AZ, NV, or CA location. Any idea who that would be?
