I put oversize tires on my truck, now the speed reads 2-5 mph different. What section of EFI Live do I go to set set the tire size or do i just use the Speedometer section....I went from 245/75/16 to 265/70/17. 2 inches taller tires now
 
Speedometer> Double click parameters then try 61671 in pulses per section...that is spot on for my 265's that are the same size as yours...
 
You could also get your speed via GPS, and enter the displayed speed and actual speed and it will adjust it for you. It's the third tab. I found this to be more accurate than choosing the size.

Is this the week you're coming in to visit?
It was supposed to be, the wife is leaving Friday, I have to work the weekend at a job site. I told her to go ahead without me.
