Top Speed Governor?


Recommended Posts

well if i'm going to do a tune i should just wait til i get my intake, headers an exhaust first right?, then tune.

Will a tune take care of a cel that is trigered by headers with no cats?


If you are going to be installing the headers and CAI soon, yes you should wait. If not, i'd still have it tuned to bring the truck to life! A tune will take care of the CEL issue also.


All SSS's are governed to between 108 and 112mph stock. It can easily be changed in the tune, mine is set to 175mph to avoid top speed limiter issues on the dyno. :uhoh:


Charlie Wheatley can help you out with the tune too! :thumbs:
