you would feel it a little if u dropped some money some some bolts on, grab a high flo cat with a cat back exhaust for like $300-600 depending on what u care about, get some pulleys for $145, take off your AC if you do this and put on a carbon fiber hood ull feel better than you will if u just running low on gas, this pretty much is the best you can do without swapping engines, turbo, or supercharger or something.
