we just bought our Uplander LT used...2007 3.9 and so far I love the power...not crazy about the electronic throttle body, but time will tell...I hear there are two different aftermarket tuning companies out there that can tweak the 3.9 for better response and more power...I plan on getting into a few mods, but nothing crazy...just better mileage and more power. cant believe the size of the first muffler...bigger then the one we use to have on the Excursion...so that may get removed and updated.....so far so good though
