Cool, feel any difference in it with the plugs gapped correctly (other than idle and revs)?

Man, I must be impatient. A little part of me starts to die if I do not drive the truck within 3 milliseconds of finishing up a mod.

I can see 3mpg from that tire. My old topper stuck up slightly above the cab and the drag it caused took 4mpg on the highway from me. on 32s with no lift I could see 19.5mpg highway. Now with the lift and 33s I see about 14mpg highway. So needless to say I am interested in your results also. Especially since I am another 4.0 OHV guy

well the only thing i can see is that the tire will disrupt the air flow in the bed from over the cab.......remember Myth Busters? lol...


maybe the extra weight also....but i am about to lose more weight when i take out my sub enclosure this weekend.....getting rid of that and back to jump seats....

that gas mileage loss doesnt make any sense! i'm assuming with a wider gap and stronger spark, you should be burning more efficiently and gas mileage should go up?!

i can't imagine the tire causing a 3mpg loss... unless you do strictly freeway driving, and even then it seems like a lot!

This coil pack is next on my list... waiting on the tax return. We'll see how it impacts a mostly stock 4.0.

Ok so I have a question, did you keep your old plug wires and stuff too? Mine have about 37k miles on them and I really want a coil pack and I would gap my plugs to .065 too.

It's not going to impact it at all. You should hold off on a new coilpack and save a little bit more $$ and pick up a chip/tuner. Then go from there.

Unless you have already done some mods to your 4.0L that have resulted in a substantive increase in compression ratio, then there is no reason at all to tinker with the stock EDIS ignition system. It is more than robust for what you have.
