My 98 Dakota 4wd 5.2 5-speed rips. My son is a tech at the local Dodge dealership. We resynchronized the timing. I fixed the plenum leak and install back of cat Flowmaster exhaust. It only has one cat. Has great power and will climb most any hill in 5th gear. Also get around 20 mpg at 80 mph and around 25 mpg at 65 mph. Though the Dakota is about 800-1000 lbs less than a Ram.
