I want to change my gears out but I drive quite a way to work.....what should I install, 3.73 or 4.10??? And has anyone used the Diablo tuner? I thought about getting one but I am not too sure I wont jack up my engine.

 

I guess I should have read some of the other ?'s first. I think I have found my answer already on the gears but if anyone has used the diablo predator I would like to know how easy it is to use and what kind of improvements it made in the power. I have a 5-speed not the auto. [sm=thanx.gif]

 

the predator is very easy to use, plug it in under the dash, and push buttons, only problem i have had is changing the rev limiter, i called diablo they said on 04s they are still updating the programmer, said keep checking the diablo site for revisions, then download for free.
