**update** Mpg

i know there has been threads before on mpg. but i'm lazy and don't want to search through them........sorry :think: ive got a flowmaster, k&n airfilter, drive conservatively and running stock 245's right now. in the city im busting out a whopping 10.4 mpg. btw, ive got a hoe with a 350 in it. would changing the plugs, cleaning the injectors give me any kind of mpg boost? or anything at all? thanks in advance
