when i first got my 08gt manual 5 speed, i could feel the power band kick in about 3000rpms. now i don't feel it till a little over 4000rpms. it seems as if my gears are just not pulling as hard as they use to. i tried to reset the pcm, by disconnecting the battry,hoping to unlearn this driving response. i sure could use some help to get my baby back to the way it was when i got her.
