Hi All

Been reading and watching in the background for awhile. Finally stepped up to the plate and purchased an: 05 D/A, CC,SLT.

I have been checking my speed with a GPS and have noticed that the speedometer it is off by about 2-3mph. Is this something that the dealer could re-calibrate? The truck is completley stock.

mine was off by 3 or 4 also. i had it reflash for my 265 tires and its still off by 3 or 4.

is it reading faster then what you are going?

im going faster then speedo says

is it reading faster then what you are going?


I am also going slower than what the speedo says.

EX: Speedo 75mph GPS indicates 72-73
