[QUOTE="BIG JUICE, post: 1515674, member: 11318"] I'm talking unloaded. Do 99% of driving unloaded. I'm always lugging with these 37" tires. I feel like I was under geared with 35" tires. Got the 3.55 gears. I know my fuel economy is better at 90 mph with these gears. But I feel like I'm losing so much lugging under the powerband that gears would actually help driveability and mpg. I don't want to be screaming rpms either. Just don't think it's efficient to be smoking when it down shifts to correct gear. Why I was thinking more air from a twin might actually clean it up and get it moving instead of regearing [/QUOTE]
