P.S. You might want to call some of these shops first, before you head over there, to make sure that they can custom tune. That is, if you are looking for someone to custom burn a chip for you or something. If you are doing your own tweaking, then be sure to ask them if they will allow you to do your own work. Some shops will do the work and tweaking for you, but you should ask what they charge per hour for that. Most of the time, they will give you a price, per hour, for tunning. This price will include them doing the work. Ask what they will charge if you do the work. Most of the time, they will take off a nice chunk for you.
