Default speedo recalibration

I have a 2005 Silverado and I hate the 3.42 gear ratios I'd like to gear down with smaller tires 265-70-17 to 245-65-17, how or where can I get the speedo recalibrated. Thanks

You can do it yourself with a programmer. Hypertech sells one that not only reprograms the computer, but you can change various items, such as speedo, tranny shift points and stiffness, etc.

Hope this helps

Eric

looking at your new tire size your speedo will only read 2 or 3 miles faster then your real speed.
