well first off this is my father in laws truck. he has no mods on it. it is all stock. the mods on the GT that i know of are bbk cai and thats it. we went from a 70 punch. he had a half a truck on me till about 90 then i puleed about a car length on him so i only beat him by a car. so my question is. is this normal for a gt or is there mods on it?thanks guys and gals
