Thanks a million! I already ordered the 4.56. I also ordered the electric fans from FF Dynamics which were the extreme duty ones. My question is, how much power will I noticeably feel with everything I have done one my truck. Keep in mind, I will be running 91 custom performance tunes, 4.56 gears, efans, along with all my other mods together for the first time.
