No front end replacements or anything heavy like that. how does he have any gearing on me? i assume you mean in the tires. i do love the tune, it feels very strong and according to the g-tech, with the servo and tune i went from 16.8 to 15.5 its impressive, i was just a little dissapointed. i put the pcm in friday and i put 450 miles on it so far so i think its learned all its going to. i figured with my other little doo dads that it would make up for the tires.
maybe your truck doesn't like the intake? i lost power when i put one on my v6 lol
wut size motors do you guys have?
Yeah, smaller diameter tires are like putting lower gears in. Kind of like going from 3.73s to 3.83s. That gives you more pulling power. Take both of your trucks to a truckstop or grain elevator that has scales and get them both weighed on the same scale. A full tank of gas vs. an almost empty tank makes a world of difference, also. Every 100 lbs equals .100 slower in the 1/4 mile, as a general rule of thumb. Your larger tires add some weight.

we both have a 5.3, and when we raced today i had 1/8 tank of gas, i guess maybe i need some smaller tires or some 4.10s. i'll try to get us both weighed in and see just how much heaver i am. maybe somebody could just donate a trick front mount to my cause...
