    The DIC is pretty brutal for accuracy. I would take its average and range with a grain of salt.

    My '98 GTP with a 3.2 pulley and a lead size 14 operating the accelerator gets ~20 on mixed highway/city (mostly highway).

    Don't feel bad. My GT gets the same 17.8mpg. Makes me sick cus I don't even drive it like I want to.

    Are the GTP's supposed to be better on gas than a GT if it is staying out of boost for the most part? My GT gets whatever it feels like for gas mileage sometimes great sometimes bad
