RPM Question

I just had my original tach rebuilt to work with the Mopar fuel injection kit. The RPM'S seem a little low. What readings do you guys get at 45, 55 and 65 MPH.
Engine - 258
Trans - T-176
T-case - D300
Tires - Stock P235/75R15
Thanks for your help in advance

You need your gear ratio too. THAT will affect things greatly.
I'd rather be lost on the trails than found at home!
