Upgrades 2002 overland

Hello all, I figure that I posted my first thread in the wrong place since I got no response. I'm a new user and am open to any input you have.

I'm looking into buying a 2002 Jeep Grand Cherokee overland and am wondering what performance upgrades would give the old truck more power and fuel economy. Thanks in advance!

I have an '04 Overland and It's already fast, It gets 16 MPG and I have a very heavy foot.

Well u can't have speed without power/torque. So again It's fast and has 265 horses and 325 pounds of torque, but If u don't run premium u will feel a difference In power, u u don't have to run It but It definitely gets up a lot quicker Check this link out.WJ Jeeps.com - Main Menu

I don't quite think you get what I'm saying, I just want more torque, I get in really tough situations out there where torque is absolutely everything to get through it.

I get what your saying but I have an 04 Overland and when I go off road I barely have to touch the pedal. But If u want even more u can get a K&N Cold Air Intake or a super chips tune for around $200.00. But remember u dont have the standard 4.7 we have the 4.7 H.O. which Is more tourquey than the standard 4.7

Re: Upgrades 2002 overland

I always start with intake and exhaust. More air in, more air out. I'm also a fan of the Superchips programmer. It's got different settings for "performance", towing, fuel economy, etc. You can pull off the road, dial it in for towing, and do your off-roading. Then when you're done, switch it to fuel economy mode and cruise home. It's worth looking into, and you can sometimes find them used. It's called a Flashpaq. It's cool because it's spelled incorrectly.
Things to NOT do inlcude straying from the OE spark plugs and/or OE sensors of any kind.
I'm running the largest Magnaflow I could find, a K&N FIPK, and a Flashpaq tune. I don't take mine off road, but am very happy with that combination.

You should consider lower gears
