They can go down to something like 600 rev/mile, which I don't think covers 35" and taller well. You can get a specmo box like superlift's truspeed or granatelli has a couple and several other manufactures. However you going to pay half of what a tuner will cost on any of those. A tuner is the way to go since you will be able to correct the speedo to a degree and tune for power or economy.

I second what ReAX says, I have always installed tuners and adjusted for tire size/ speedo w/ them.

I don't know about SCT, but superchips, edge and Sniper can adjust the speedo. Since SCT is or was part of superchips, I'd expect them to be able to do it too.

I bought a Superchips speedo tuner. I got wildly ranging prices from shops and dealers for a recal and decided that buying my own tuner would end up paying for itself.

I just ordered the Superlift TruSpeed speed sensor calibrator. I'm curious to see if it works.
