    Default 06 rear end gear change problems

    06 silverado 5.3 flex fuel. Changed gear from 3.23 to 3.73. Now have abs light can't get rid of. Used hypertech programer and went quarter inch at a time on tire size no luck. Also says I have a p0045 code but I don't have a turbo. I can use some help.
