Thanks in advance to whomsoever replies! I have a '04 F150 w/ the 5.4 3V Triton. I have an AFE cold air intake w/ the Silver Bullet throttle body spacer. Edlebrock headers, true dual exhaust w/ Dynomax Bullet Race muffler. I have the Graphon with custom 91 performance and custom 91 tow tunes coming soon. I had to upgrade my edge evolution so I would stop running lean. I also run 35" tires. Should I change my gears from 3.73 to 4.10? That is what the new Raptors have w/ the 35" inch tires. Also, is there anything else I can do for better performance? How about a supercharger? Worth the money? Again, thanks to those who reply.
