I live in rural Texas and have limited access to tuning services. I am thinking of purchasing a tuner because I have two ls projects and a third engine waiting for a project. I would like to do simple things like be able to change the gear ratio tire sizes ect. I don't want to get too deep into it like changing air/fuel ratios.

Do you guys have a suggestions on what would be a good programmer for this or should I steer clear of this all together?
