how to tune?

ok I am fairly new to tuning, and I'm getting to the point where I'm getting into the internals of my engine. but I have one problem for tuning my car... there are no Dyno's around here for public use as far as I know... and I want to get the best performance out of these expensive parts as I can... what can I do?

get a gtech performance meter and a wideband 02 sensor and if you dont already have one, a something to control the air/fuel mixture...such as a apexi SAFC. it will be very very crude, but ive heard those gtechs are actually pretty accurate.

or just check here. there are dynos even in alaska.
