SC UL8R1990

Ever since i installed the 145mph speedo on my 90SC 5speed the speedometer is showing too fast. It's really bad( about 5-8mph off!!!). What could have caused this? I already know i have shorter than stock tires and it should only be a 3.3% difference on the speedo gauge. so thats barely 1 MPH at any given speed between 0-65. Is it possible that my SC has had gears installed? is it possibly something wrong with my 145mph speedo?
please help, this is really starting to bug me
