What do you guys think is different between the motors of the new ok and the model years that hypertech supports?

Interactive fuel decel shut off which would be a change in the computer, another change I know is the coil packs or something like that are a bit different. This change is easy to see when looking under the hood at the intake manifold area.

The newer KKs get I believe 1 or 2 estimated mpg better than the older KKs which leads me to believe there is a bit of a difference in the computers. It's hard to find the exact differences. A few of us have been curious about this for a while now.

It's pretty ridiculous how hard you have to try to get those estimated EPA numbers. I believe these tests are done on some sort of dynos, but I'd love to see these EPA guys drive a KK and actually achieve the numbers they post.

There was a show, might have been Top Gear, but they tested three vehicles and had normal people drive them and were all able to hit the EPA numbers with no problems... There was no Jeep Liberty in their testing.

Next mod: Something super aerodynamic?

3 conduits clevis lift per side up front
1/4 top plate

Tera flex bump stops up front
OME 2948 Rear
OME 2927 Front

hopefully will give a bigger lift than current setup/


Just wondered what the part number of the front struts you used were. I am going to do this lift on my 09 KK Liberty.

Front shock numbers are all the same If you go to say jeepinbyal you can get the bilstein, OME or Ironman ( which are a longer shock) but part numbers are right there
(also same for a KJ )

04 KJ 4.5 JBA lift, 03 KJ 2.5 JBA coilovers,
