welcome, as nick stated above, it is a JEEP not a car. i correct people who call my jeep a car regularly and they get all angry "its not its own class" ill reply with "you bet your ass it is, there a car, truck, van, suv and JEEP. it IS its own class"
how bout lowring your gears? that will start with more power. what tires are you running and what size lift?
