Hi all i have a 1985 Firebird 2.8 Liter V6 and the speedo only reads to 85 mph and the car only hits about 95 mph tops cause of the governor, is there any like new ESU, or a chip i cant buy and install to stop the rev limiter and possibly make my car quicker?

 

Try the DFI ECM catagory. You Have a little better luck in there with this question.
