Re: Superchips in a 4.7L HO
I don't have the HO motor but I'm going to chime in anyway. I just picked up a superchips flashpaq for my 01 a week ago and I can tell a difference. Better throttle response and it definitely seems to pull harder, although I have yet to try the 91 octane tune.
While that may not hold true for the HO motor, but the transmission updates should. It feels pretty normal if I take it easy, but the shifts are much firmer when I stomp on it. It also holds the gears a little longer, less gear searching when cruising down the road up and down hills. I feel this is where it makes the biggest improvement.
Check this out, he has the HO: http://jeepgarage.org/showthread.php...ghlight=disney
