I forgot to ask the dealer when they did the work, but has anyone calibrated their speedometer after putting on bigger tires? Is it hard?

Use a GPS to see if the speeds match. If not, you'll need a tuner like Jus mentioned.

Dealer cant do it I already checked with them. Some wheel/tire shops MIGHT have the required programmer. If not, Hypertech makes one and it runs about $200. The Pulsar can also do it, as well as offer canned tunes for about $500. I'm leaving mine the way it is for the moment, but will be buying the Pulsar in the future. Right now if my speedometer says 75 I am really running 80.
