How important is it going to be to get my car re-tuned after install the modified rockers and headers? the rest of the mods are in the sig
 


dont get on it alot with headers and rockers you will prob run a lil lean....i put in my rollers and im running slightly rich, which is lucky and weird but if you have an aero keep an eye on your 02's if they are under 900 at wot stay off the gas unless you wanna chip a piston ...
 
you wouldnt NEED one, but itd help you out a lot to make the power you should be making with them.

You paid the money for the mods. If you want to see the difference and get the most out of them, you should get a tune. Not to mention you have no idea how far off your car will run, or if you are getting knock at all.
 
If its already a custom tune, it would be wise to check kr or get it tuned in again. There is power to be had yet.
