i just put in a new CAI in my '04 v6(auto), and it works great. now, i was thinking about putting in new gears. ive heard 4.10s work great, but i dont know too much about this mod. Ive also heard that the gears messes with the speedometer. if so, what would i need to do to fix this up.

If i could get your opinions and tips for this mod, it would be great [sm=feedback.gif]

 

speed cal or a chip will fix your speedometer. you'll notice a nice difference with the gears though.
