it comes stock with 260+ HP. however, you can get a stillen superchager for the 4.0L v6 engine and add almost 100 Wheel HP to the truck. headers and exhaust will ad somewhere around 20 -30 more hp. you can also get a lightweight crank pulley that will add another 5 -10, an intake manifold spacer good for another 5 -10 hp, and a lightweight power steering pulley for another 5hp. total is you're looking at somewhere around 400hp at the crank.How mutch horse power can a new 07 x tera put out?
