Perfomance upgrade

I have 2016 SR5 with 4 cyl, 2.7l. How can i improve the trucks performance? the throttle response is slow especially when im going uphill. Im losing power and torque im just thinking to drive without florring the gas pedal. I dont have lots of knowledge about engine performance so thank you in advance.

 

Lce header gets my vote

more upgrades in here, just make sure theyre compatible with 3rd gen trucks. Havent had the time to separate them all out
