the intake manifold you have is the same as the high output ones on the jeep 4.7's. you can upgrade tot he 08+ 4.7 manifold but you need to purchase the adapter to use the cable controlled throttle body.
chithead i have the superchip flashpaq for my 4.7 and dam it works better than advertised,It has all sorts of user adjustable mods,such as shift points,fanstart and stop,tire size adjust, it will also do 60ft times,1/4mile times,. Last week got an update from the web site went straight to the truck put it in and away i went.I posted this before but I SPANKED a stock HEMI in the 1/4 MILE. now thats power from a 4.7 liter
hey chithead only have the tuner in about two weeks, don't have any times yet but will soon, It's absolutely hillarious when an old man in a stock lookin 09 pull's up next to some young guy in a moded up hemi thinkin he's all that next to his girl friend and i wave by by and sail on down the road and he can't catch up.
