as far as fuel efficiency goes... is there any modifications out there or anything that can help it get a littleeee better?

CAI and exhaust.

Sure there is, buy a V6 Grand Cherokee. =P

Don't start it.

The same thing i did for my H2...1st-Add 2 ounces of isopropyl alcohol for every gallon of gas...then, and this is the important step, to simulate the "displacement on demand" feature of the Caddy, pull the plug wires for cylinders 2,3,5,6 and splice in a switch. Then.when your out driving, shut off the switches. Instant double of your MPGs...Or you could just not have bought a 425HP 6.1L AWD truck.

I think you have to approach this from another direction. Enjoy the power but get your Gas as cheap as possible. I signed up for a "feul perks" program with my local grocery store. They give me money off per gallon for purchases made at the store. See below cost of a fillup with premium

You gotta love Giant Eagle. Now its 20 cents off per gallon for each $50 spent on gift cards. I'm doing all my Xmas shopping there and driving for free for months. I had $4.70 off per gallon at one point.

I don't know how Giant Eagle do it frankly. What do they do if you have $4.70 off per gallon - just apply the balance to the next fillup?

Incidentally I ordered a passport 8500

I'll let you know how it works

With my GSM CAI and Zoomers I get roughtly 16.5 to 17 mpg going around 75-80 mph.

Don't start it.
haha!:eek:

I don't know of any place that does this, but if I knew of one and had the opportunity locally, I would hedge my fuel for like a year.
