I tried to search but couldn't find anything on this although I'm sure I've seen it before.
Anyway my original tires were 255/40/19 (I think) from the original Brembo wheels. I'm now on 315/35/20 on the rear. I know my speedo is off (that's what she said) but can't figure out where in the SCT I can make an adjustment for this. I contacted SCT and they said that would be only for preloaded tunes. Under Adjust/Options or something to that effect, but I find nothing.
I had a preloaded tune then dyno. Anyway can this be adjusted?
