I live in California. How do the different tuners effect the California Smog check?

 

All Hypertech Max Energys are C.A.R.B. certified so you would be fine tuning your truck with one. What year is your truck?

 

The truck is a 2007 F150 w/ 4.2 6 Cylinder engine.

 

They have started smog checks here in Austin, Texas (Travis County). I just had my vehicle inspected and it passed with flying colors. This was with my bolt on's and my Superchip set in the performance mode. Worse case senario, re-program to stock before they hook up the sniffer.
