there are plenty of people running around these forums willing to help people tune. I have helped a few handfuls of people understand the basics of tuning and even helped via email with bin corrections from data logs they made and explained why the changes were made so they could learn to do it.
I believe having a scan gauge in the car is very very important. But being able to actually change the tune and do something about the problems that are found are just as important.
I originally was just going to buy an aeroforce. I had a friend that strongly recommended the powertuner. He offered to help me just learn and do my first few tunes. This was all the push I needed. Back then there was about an 8-9 month back order for the tuner. In that time I saved up more money and got the aeroforce anyway. Watching the live data every data helped the learning curve and prepared me for when my tuner showed up.
there is also the less expensive option of the ScangaugeII they have them at autozone even and are about half the price of the aeroforce. you will need to research and add in the PID for KR and fuel trims but it is still a great unit. I had one after my first aeroforce died of old age and florida heat. It now lives in my wifes lancer and I once again have the aeroforce. (sent it back for repair and upgrade)
