Thanks for the responses everyone, Area47 is going to tune me, he only lives an hour away from me. He did a great job on another car of mine. The reason I was wanting an unlocked tune using HP Tuners was to allow me to later on do minor tweaks like change shift rpm, change TM parameters, etc. I just don't feel confident enough yet to do the main fueling and timing adjustments.
