we were thinking about getting a new 4 dr and went for a test drive. its been awhile sinse i had a jeep and the last one i have ever been in was a friends tj from a few years back and it was readily good on acceleration. the new one was horrible. what are you guys doing to make it more powerful? does a chip and cold air make a great difference? still havent canceled it out, but the lack in power is scaring me away from it. i love the jeep though.
