07 GMC 4x4 Speedo ?
I have an 07 GMC 4x4 with the 7194 predator. I'm running 295/70/17's and have already made the adjustment the tuner. My ? is now my speedometer seems like it is too fast now. My GPS shows me going 4 miles under what my spedometer shows. Is it possible for the GPS to be off or do i need to play with the sizing some more?
