8.1 upgrades
i have an '02 8.1 Allison and don't get me wrong, I love it but at the same time I wish I could get a little more out of it. Is there any mods I can do outside of a K&N and magnaflow cat back that won't cost a fortune. Superchargers are great and new heads and intake are too but I'm not sure I wnt to spend more in mods then I did for the truck.
