If you're serious about learning to tune, you'll need to invest in a wideband AFM (obvious, and a costly purchase.) Round up as many books as you can find dealing with thermodynamics and engine theory. There are a few books in print that deal with engine tuning, though there is NO single definitive how-to manual to tuning. You WILL have to use your head and think a lot during the process of educating and enabling yourself to successfully tune your car without creating a lot of broken parts in the process. Whether you tune the car or somebody else does, there will be an investment in either/and/or time-money-intellectual labor on your part. You're doing the right thing by asking questions BEFORE you buy, though. I think you're on the right track.

Find someone that can sit and help, I tried the same thing you are trying, and by luck I didn't destroy my motor. I finally got a little help, and it made it a little clearer.
