Correct Speed

[StoreKeeper99Z28]

Right now I have 255X45Zx17 inch with 4:10 gear and my speed reads 75 at 1800 RPM'S // 70 1600 with 26.1 set in the PCM.


Does this sound right?

Any input would we greatly appreciated


Thanks in advance

I always confirm my setting with a stop watch and cruise set a specific speed and go between 2 mile posts on the interstate. I use 80mph/45 seconds and 60mph/60 seconds.
