Does anyone know what the mph limiter is set on in the 2002 4.8 silverados. Also, what do i have to do to make my 4.8 a 5.3?
thanks

 

The governor for the 2001's is ~97-98MPH

 

GM speed governors are related to what speed rating the factory tires are.

my 02 shuts down at ~97-98

hopefully fixing that soon <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
