EMC?????? I have a question about the EMC on a PPV. I installed a super chip, do you know if this took out the police package program?

I just upgraded my Tahoe with new rims and tires, went from 17 to 22. And I noticed that my speedometer is now 6mph off at city driving and 10mph off highway driving. Does anyone know how I can correct this?

Thanks

Just wanted to take this time to say Hi to everyone. This is my first Tahoe, and I have great things in store of it. Looking forward to the advice from everyone.
