need to get better gas mileage and/or more hp

wruth · May 23, 2002

i have a 2000 silverado that is lifted on 36" tires. i was wondering what mods you have done to increase gas mileage and hp. i have the hpp3, flowmaster 50 series exhaust and that is about it. i was thinking about under drive pulleys, but i dont know what to get or where to get them and i was also thinking about regearing it but i was told that doesnt improve gas mileage and it is a littel out of my price range. I am also considering the fipk gen 2 or the upd intake. any other suggestions please.

You won't see any gain from underdrive pullies unless you spend your life at a race track. Otherwise, if caught in a lot of stop and go traffic it can acutally cause undercharging at extended times of idle.

What gears are you running? I know it's a 4x4 so you'd have to replace both gearsets, but gears can wake up a vehicle, torque converter, all the way up to heads, cam, supercharger, turbocharger, nitrous.

im looking for more gas mileage than hp right now, once i finish school i might change that. im running 3.73 gears right now and i went to get a quote on gears yesterday for front and back it would cost $1456.00, i dont really have that much money right now, i still need to pay off the truck

Do you have a tonneau cover? It helped my gas milage quite a bit, and I think RyanbabZ71 had the same result.

other then driving like a 90 year old lady, there isnt much you can do about gas mileage with a lifted truck. even with my non-lifted 3/4 ton. so i gave up and got my Turbo regal for my daily driver, gets better mileage then the truck and easier to park then a ext cab long bed pickup, plus its a quick car.

for the most part just be extremely easy on the throttle, slow down, etc. you might see a slight improvement.

i know that doesnt help you much, but oh well...
