    acrespo3,
    They are both correct. before 2006 the I6 engine had 275 HP and 2006 it was increased to 291 HP. There are lot's of mods you can make to help improve performance of the engine but keep in mind that the on-board computer has the final say on whether those improvements make it to the rear wheel so in order to get the most out of any physical mods you make you will most likely have to either "Chip" the vehicle or pray that someone comes out with a register programmer for these I6 engines to allow for tweaks in it's settings.

    Hope that helps!
