You could see what other vehicles have the XLE motor in it, and see if any performance parts are made for that vehicle. Some things might need to be modified to work, but the priciple is there. I would recommend starting small with something like an underpulley kit to get a little bit of ooomph lol... you could also look into aftermarket chips, air induction products, and other small things to gain HP. I believe that an underpuller system will add around 15-25 HP, just by lightening the workload on the engine. Check it out....
