which engine?
removing vacuum lines will not help performance only hurt emissions. The 00' up 2.4's have no EGR and no 2.4s have MAFs. Grinding intake parts and cleaning them up is risky and usually pointless on the TB or tubing. The rest is pretty specific to having an intercooled turbo, which, obviously, you do not have on the alero so its not applicable.
For ~$15 you can get 1/2 tank of gas, but not much else, maybe a couple of cans of seafoam.
