Ok I'm kinda new here. I have been on many car forums but haven't looked too much into the SHO forums since I just got the car. I see a bunch of people doing methanol injection and everything. Is there a way to get some more boost and increase performance without getting into separate fuel sources? I doubt I will ever be tracking the car so that being said what mods are best to increase performance on my daily driver? I would also like to not completely destroy my fuel economy. Also how does the warranty work with mods(all or nothing or will I only void certain parts)?
