change your oil
new oil filter
new air filter if running stock (or clean your K&N is that what your use)
spark plugs (gapped correctly)
new spark plug wires
check your trans fluid level and cleanliness
check both your serpantine and supercharger belts for firmness and excessive wear
check your power steering fluid level
These are a few things to check/replace I'm sure others will chime in on additional things to do!
Good Luck!
