I do have larger rear tire (255/40r17) but i always felt speedo read 1-2% low on stock 215/45R17 tire. So it is probably more accurate now otherwise increase MPH about 2%. This is with a 2017 AUTO IC Sprintex 69mm pulley WMI+92octane on 255/40r17 all season tires.
Curious what other people are logging.

Once I get my car buttoned back up I will do a run as well
