i installed my knn intake this after noon. everything went good. and now about 3 hrs after the installl. my speedo is stuck at 25mph... is there anyway to reset this or anything?? i need this truck tomorrow and a speedo would be nice.. and a final question. does my speedo problem have anything to do with installing the new intake?

 

This Is A Common Problem, The Stepper Motor That Operates The Speedo Has Gotten Stuck, The Only Fix Is To Replace The Whole Cluster, Gm Doesn't Service Individual Components.

 

yep mine went out at 30k just incase try unhooking the battery and rehooking it up..

 

and if it helps it used t hang up a little at 45-50 but not 4 more than a second.
and how much do those cost?

 

idk mine was warrenty.
