SPEDOMETER LAG

[GIT R DONE 05HD]

WHAT KIND OF SPEDOMETER LAG CAN I EXPECT ON MY 05' K2500HD DURAMAX GOING FROM A TRIRE SIZE OF 245/75R16 TO 285/75R16? WHAT WOULD THE PROPER CORRECTION BE? I PLAN ON INSTALLING A 2" LEVELING KIT ALSO, ANY POTENTIAL PROBLEMS OR THINGS TO BE CONCERNED ABOUT?

Your going to need a programmer to fix your speedp, like a Hypertech.

7.8%

to go 55 mph indicate 51 MPH

to go 65 mph indicate 60 MPH

to go 75 mph indicate 69 MPH

 

In other words, it probably won't get you into trouble until you get above 70.
