I have a 2000 Camaro Z28 M6. Trans broke one night after work, so finally got the car home pulled the trans, and sent it to Hawks Motorsports. Paid a very pretty penny to fix problems and have their "Stage 3 Viper Extreme Upgrade Kit" done to it. Ever since speedo has been off and I've tried many different ways using HP Tuners to fix the problem. I was hoping someone else has done this or can point me in a better direction. Thanks.
