You need to start your own thread in the correct section, not reply to other peoples threads.

I moved your post to a new thread this time.

 

How do I post where do I go not familiar with
Forums at all

 

Mine was about 10% off, thru the whole speed range, came stock with 225/65 15s. (Tires) Now with 30x9.5s, its probably a wee bit further off, but I know its about 7-8mph fast on top of the percentage. I swapped clusters, and didn't pay attention to where the needle sat before swapping my odometer in. So it dummy proofs me. Now at 65, I think I'm hauling ass...but only just over the speed limit. Why you want to fix it? Use a GPS, figure out what actual vs. indicated speed is, and run with it! What size tires you wearing? What's the nom plate spec for tires?

I want to fix it because I dont like to go 80 on the speedometer but actually on 70 and rpms at
3k tires I have are 31×10.5×15 Hercules mt forgot to mention speedometer sits on the 4mph mark whether its running or not what can the problem be the gauge cluster or the speedo cable

 

I used a GPS to find how off it was

 

Read through here : https://www.yotatech.com/forums/f116/sr5-gauge-cluster-swap-how-pics-179106/ , see if you can work out how to adjust the needle. ONLY TURN IT COUNTER-CLOCKWISE. Otherwise, you'll trash the return spring, and it will be off. Which could be the issue already. Is your truck a DLX or SR5? And at 70, you're gonna turn about 3k rpm. It's normal. Ain't a Ford. 22RE? They're ok with revving a little bit.
