Hi, I am new to the forum and am wanting to do some performance mods to my 04 5.7. I have been looking around and here you know a lot about cams. I am thinking possibly a cam and the maybe new pistons, etc.. And maybe on to supercharger or turbo, or something along those lines. What I want to know is what type of cam I should get, any other things I will also need, and how much it will cost. Also I am going to be getting a K&N CAI, and edge CTS tuner. Will that tuner be good with cam and or the other mods I want to do in the future. Any help would be great thank you.
