If you are getting 13 mpg. I wouldn't touch anything that's very good mpg for a 460.

A cat delete won't do anything but make the exhaust louder... oh and make the truck an excessive polluter.

and that throttle body spacer does absolutely nothing.
they are a scam designed to make buyers wallets lighter and the sellers wallets fatter.

how? it does absolutely nothing but make the throttle body 1 inch farther away from the manifold.
it does nothing for fuel atomization, because the only thing that passes over it is air.
you THINK you got better mileage from the TB spacer, but in reality it had nothing to do with it.
