I'm going to check the speedometer tomorrow, however since the wheels are stock size, I'm not too hopeful that's going to reveal anything. If the speedo doesn't match what the EDU is expecting, then it could cause a problem. However, changing tire size will not cause any variation between EDU reading and calculated fuel economy, because they're both seeing the same thing. Take your case as an example. Your speedometer is reading 10% high. Your EDU is reading 10% as well. And so is your odometer, so your calculated readings will also be 10% high. In my case, my calculated readings differ from the EDU, so the problem cannot be anything which is common to the EDU and calculated readings.
