Speedo not correct even after changes in Edit I made the changes correctly in LS1Edit. I put in 4.1 as the gear and 26.4 as the tire diameter. I got the tire diameter off of Hoosier’s website. However, my speedometer is off by about 7 or 8 mph. Example, when I’m going 67 according to my speedometer, I am actually going about 74 or 75 according to my wife’s car and the speed check trailers.
Anyone else have this problem?

Yep, I've had that problem with several versions of edit. The problem has been improved on in the later versions, but it's still there. I adjust mine experimentally using mile markers on the freeway to fine tune it.

Well, I'll measure the circumference and then compute the diameter I guess. What psi should I put the tires at when measuring the circumference and should I measure with the tires on or off the car?
At which speed ranges are we talking about? I think mine is off too, but I was under the impression that the tire diameter increased as speed increased. So that would mean you are traveling faster than the VSS reports, right?
It's cool to see the speed trailer numbers flashing when I take that 35mph S-curve
