I'm to the point again where I HAVE to do a little more tweaking on the old girl. With fuel prices being as they are I'm try to do stuff that'll improve fuel mileage as well, and I don't want to open up the engine cause it ain't leaking anywhere yet.

I already installed the F-250 Inlet tube, and it has helped pick up just a little power at speed, and about 1 mpg. I'm also currently running a custom 2.5 inch cat back with 40 series Flowmasters.

I think my next mods are gonna be the Bassani Off Road H-pipe, electric fans, and the 30% underdrive crank pulley. Just wondering if y'all have any input or warnings on these modifications before I start spending money.

Thanks.
