Hey everyone! I'm pretty new at this so you will have to bear with me, but I was wanting to know what is the best tuner for my car? I have a K&N CAI. Also, I was wanting to know if it would be benifitial toget a newthrottle body with a throttle body spacer? And what type of gears work best with auto transmission?

 

3.73 gears seem to be the favorite with autos here. check out www.brenspeed.com and get a custom tune with your tuner

 

negative on the throttle body and throttle body spacer. I have the spacer and it does nothing except make a whistling noise which i can no longer hear due to my loud exhaust. and the throttle body actually loses power with a tune is what i've heard. the guy that put my mods in said the gains from the throttle body is negligable. my livewire tuner is the best all around tuning device you can get, check out their website. 3.73 are good w/ auto, but 3.90 or 4.10 are good also.

 

dont change the TB or add a TB spacer, useless mods.
3.73 gears are great for automatics

 

welcome

 

the livewire is expensive and has bells and whistles that arent worth the money over a XCal2 or predator
