performance mods for jeep grand cherokee?

[tobaccogrower]

took our 2006 grand cherokee snowmobiling this weekend(truck blew #4 injector line!). it pulled our 14 foot enclosed 3 place trailer ok. it needs a little more power on the hills. my question is there any performance mods out there for this jeep? it has the 4. 7 v8. thanks... ... . james

jeepsunlimited.com is a pretty good forum to look for these items I use to have a 95 that was tweeked. Bad thing is its as addictive as this one.

I have a Superchips programmer on my Wifes 02 4. 7 Cherokee and wow, that woke it up big time. Its alot more fun to drive. Its funny, the wife loves it too, but now she wants more! I wish I could afford to put a more "efficiant" engine under the hood... if you know what I mean... :-laf
