Has anybody chipped the 4.0 6speed. Would like to know how good the MPG is with it. MFG is claiming 3 to 8 more MPG and up to 75hp.

basic physics says u can not get more MPG and HP at the same time
its trade off if that was teh case we all would have 1000 hp engines and getting 100 mpg

If you were to get more HP would it not take less fuel to pull.

how do u think u get HP? U get it from doing 2 things one changing the compression in the engine by replacing pistons cams and all that kinda good stuff.
Or u add more fuel which is what the chip will do. as i said basic physics
