withthe 4:10s I spun through the first couple gears, making it feel slow. THe gas millage wasnt too good either. The gears felt too short to me. When I went to the upgraded IRS, I got 3:73s. Not as much spin and it pulls longer in each gear. I get 26mpg on the highway now as well.duh09 said:Scarface said:I went from 4:10s to 3:73s... Im very happy I did.
Explain yourself! I'm thinking about doin it because I have some gear whine...
