...honestly, i don't think the 4.10s themselves really cause the fuel to go faster: i CAN keep my mpg the same as when i had 3.55s IF i stay off the accelerator. that is much easier said than done since 37s + 3.55 = slow and 37s + 4.10 = much faster. 
every now and then i just can't help myself and go blasting out of an intersection because it's summer and i can and i love showing off my truck
