[QUOTE="93 saturn sl2, post: 3209941, member: 558890"] lolololololololollol but to answer your question... You cannot help performance and save gas at the same time. If you want to help performance heres some of my suggestions. 1. get the U-bend replaced with a straight piece of pipe. GM decided that they wanted to mount the rear O2 sensor vertically which results in the picture below. Replacing the u-bend will free up some HP. [IMG]http://www.pfyc.com/mm5/graphics/new/wb5001.jpg[/IMG] 2. Get a CAI or FWI (fenderwell intake) Id suggest the NAIOA FWI, but I think they stopped being made so they may be hard to find. 3. reprogrammed PCM. They're only $100 and its well worth it from what I hear.
