you can do it yourself , It is the high road but you learn how it works, MS is a diy and thats where the fun comes in. Besides its a never ending learning experience. I recommend getting the harness from DIYauto tune and its only like 10 wires you have to send out injectors, coolant, tps, ignition and setting up some relays. Read up and try it out.
