fair enough..........do what you have to do. I understand not having the money for it. The way I look at it personally( and I dont even have a tune yet-wish I did though) is the $300 more it costs you could save your motor.......just me being paranoid though. I have seen that tunes in the Rockford, IL area can be had for a base of $100 and $25/hr ....fwiw. I think I am going to go that route. That still would only be a total of $300 for an all day tuning session.
