Another question......
I have a 2012 Camaro 2SS/RS LS3. I currently have long tune headers with no cats. Cold air intake, ported throttle body, APEX race scoop, and Vitesse throttle controller. . What kind of gains can I expect with a tune? With all the mods, I am getting about 9-10 MPG in town and 18-19 on the highway. Will a tune improve gas mileage at all? What is the difference of bringing my car to a professional tuner or using a hand held tuner? Will I be able to get the same results?
