Personally, I have lived in hampton roads area for 21 years and I have to say that ED CLARK is the best tuner in the area. He sells the new 4 bank switch chips by Superchips Custom Tuning and he tunes the chip with a laptop computer so that he can correctly adjust all parameter of the car.
Chip, tuning and install is 325 dollars.
Many mustangers in the area use him to tune their cars as he is simply the best.
If you need any information or would like to meet up with him i know him personally as well as where he lives and he would be more than happy to even tune the car at his house.
