Bought an 08 Chevy 2500 with 18" wheels. No help from dealer on speedometer correction. Found Hypertech on internet and was somewhat hesitant about ordering it. Got it anyway, programmed it to my vehicle, measured wheel as told to do and plugged the programmer in. In about 2 minutes DONE. Speedometer is now "RIGHT ON". Great product.
