First off like to say the family genes of being mechanically inclined must of skipped a generation because I am mechanically declined. I am in the process of putting on the dragula 2-1 exhaust and a heavy breather. I was told that I need to get a tuner and get it dynoed?? So I have done some research on the web and see that some people say you can get a tuner and not Dyno it and others say you need to do both. What exactly is a tuner? Any recommendations for the setup I have? I will eventually be adding some cams but that's about as far as I will be going.
