i have a 06 gt 4.6 3v thats been a thorn in my side. bolt on mods are long tubes, x pipe, 3in exhaust with flow thru mufflers. car has new aftermarket coils, wires and plugs. also has a dual blade ford racing throttle body. im having issues with the throttle input, its jerky to throttle input. i bought the car like this, previous owner seems to have changed some things and got fed up with it. if someone could give me a hand and tell me what i should change that would be great, if you want to make your own changes to the file, go right ahead. id just like the car to be responsive to the foot and have the torque. the car is a manual, and the internals of the engine are stock. mikesgt.hpt
