What is a tune?

 

messing with the computer to get the most out of your mods.

you can do it by:

handheld tuner-bad idea
efi live, hp tuners-ok if you know what your doing
full chassis dyno- best and most complete solution

if you ask that question, then rule out the first two. a chassis dyno tune is around $500

 

Dang. I was always thinking tune up. LoL
