Has anyone here had any luck with using a tuner? My 2004 TJ has about 145000 miles and while it seems to have good power, it seems to fall off rather quickly on even small hills. Is this something any of you would recommend or stay away from?

He put the 4.0 in the profile, so we can go off that for now.Which engine do you have?
I’m not understanding what folks are expecting from a straight six with less than 200 engine hp and oversize tires?!... it seems to have good power, it seems to fall off rather quickly on even small hills.
What is the difference between a tune and a performance chip? How is a tune installed?
Why is that? Most all other modern engines have room to improve except the 2.5 and 4.0?You can give your Jeep a tune-up but there are no tunes that will make any difference. If you want power you need a different rig. The 4.0, 2.4 and 2.5 are not capable of any real power by modern standards no matter what the tune.

Aren't the TJ 4.0s just an updated AMC I6 from the 70s? So a 25 year old design when the first TJ rolled off the line and a 32 year old design by the time the last ones rolled off the line.Why is that? Most all other modern engines have room to improve except the 2.5 and 4.0?
You can buy trucks today with over 500hp, tweaking our Jeeps so they can keep up with a 10 year old Toyota Camry is stupid.
Now you're just making a fool of yourself putting your assumptions out there trying to represent me and my thoughts on tuning. I haven't done anything with my Jeep for the simple fact that I have other priorities at the moment I do in fact have every intention of having my computer reprogrammed. When I am ready to and can financially afford it.Put your money where you feel there is value. In 4LO I never want for power and for me that's all that matters. As far as tuning for higher octane gas, not a chance. I really enjoy buying the cheap stuff. Seems like @reddvltj and @Wildman don't have a tune either so I guess they don't think it's worth a damn either.
So true. My brother bought a new Ford F-150 3.5 Ecoboost and tuned it. It's lifted on 35s too. That thing is a rocket compared to my Jeep. The tune added 125 hp and almost as much torque. It's putting out around 445 hp and 500 ft lbs of torque now. I'll never drive that thing again.You can buy trucks today with over 500hp, tweaking our Jeeps so they can keep up with a 10 year old Toyota Camry is stupid.
I am expecting to Fuck off the stupid pre cats and o2 sensors on my 06 eventually! having a 6 cylinder gas guzzling "Brick" with emission controls that are just "The Emperors New Cloths" Plus we dont Smog or MOT in Australia ( for our UK brethren) But I do want to ask about exhaust smell for those that have deleted their cats.He put the 4.0 in the profile, so we can go off that for now.

edit; I’ll even take the oversize tires out of the equation. It’s a Jeep.
