need some questions answered.

i just bought a 02 z71 tahoe has 170000 miles and i want to do some work to its motor wises. i would like to know what kinda things i could do to it for more power and is that to high of milage to start motor work. i had a 92 camaro with a 350 that i put alot a work in the motor. but it was one of those cars that would never get finished.
im in the process of giving it a good tune up spark plug ngk 2238 are good from what ive been reading, i changed the trans fluid, and filter i have a k&n air filter, oil change, fuel filter, brakes all around. i still need change my diff. fluid to, but if you guys know of anything else let me know and if you have any information about giving my tahoe a little more any power please let me know. thanks

check the brake lights and the horn, not 100% but i think if these dont work the cruise wont work either
