I currently have tuning by a shop that doesn't do the tuning anymore. I just recently removed my lift and thus went to a smaller tire size. I tried calling another tuner to just buy new tunes. Well they can't turn off the EGR, even though there isn't one on there, so my check engine light will come on. Is there a way to change just tire size with the current tuning, or will I have to suffer with the CEL being on all the time?

Hypertech has a device to change only the tire size.
Super chips has FlashCal.
Simple search for your question is available online.
Pretty much any of the off road shops are able to do this, even your dealer.

I used the Hypertech when I went to the 19.5s. Great little tool that works wonders.
