nope. the 3.9L engine was good for um...nothing. as said, abysmal performance, power of a hopped up 4 cylinder, with the gas mileage of a larger V8.


make the truck lighter, swap the gear ratios around, maybe try a custom tune on the engine computer? I think the factory tune was pig rich on these things so that there was lots of gas to give the cat converters something to "chew on" and make them more efficient at their job. dunno if that's true or not though
