Do you have Injectors? If not a set of RV injectors will help you squeak alittle bit more out of it.

 

arent injectors expensive to put in though?

 

A set of 75hp injectors and a Edge EZ.

 

No they a set of RV 275 would be a few hundred bucks and you can do it yourself in a about 2 hours or so

 

smaller tires, less skinny pedal and like luke said and ez

 

the tires i run are very cheap so i am trying to avoid downsizing tires. what rpm do ya'll run ur trucks at? and whats the HP rating on the RV275's? thanks

 

what are your stock gears?

I'm running 4.10s Lt 265 75-16 tires around 2000 rpms,@ 55 MPH 20 mpg on hiway,EZ on the skinny pedal

 

i went from the factory 245-75-16's up to a 285-75-16 and noticed a hair better milage it dropped my rpm at 70mph

 

i turn around 1800 at 75 mph down the black top but i do not have an acurate odometer or speedometer. i rely on my programer to tell me my speed. anybody know were i could get the different gears in the speedometer cable on the transmission end so that my odemeter and speedo would be accurate? thanks for the help
