Im going in for a smog test either tomor. or the day after, my question is should i switch my tune back to stock on my sct tuner, its tuned to 91 octane and all my mods listed in my sig....and last time i had a test i passed, but i didnt have a tune and i had a few less mods then i do now....so keep it with the performance tune, or switch back to stock?

 

I dont know about the tune, but is your Flowmaster system catted or o/r? if its catted you will be fine. and everything else has to be "CARB" stickered... if you have a carb sticker on ur CAI you will be fine, i dunno about the spacer or throttle body or all that other stuff.
