    A little bird told me you can do magic with cars. This same.bird also says you are a jedi master of your trade and can make the impossible, possible! Please, I can do without darkside mind tricks. If you are indeed the chosen one, “the prophet” please summons me and the horse power Gods and we can majestically, take sharp apexes to a new level

    I await your transmission… No pun intended…


    How much do you charge to tune a vehicle, I have an 04 corvette c5 with vararam ram air and non muffler exhaust. I run a 12.6 1/4 mile looking to hit high 11’s eventually, I am even considering just a 75 shot of nitrous unless you suggest otherwise. Thank you for your time.
