I feel like the tune is right, but that the speedo is inaccurate. a problem that I exacerbated with changing the rear tire size I did not do my own tune and do not want the equipment as a means to keep me from screwing with it all the time. And really do not want spend a lot to redo the tune

Brew City the 1/2 tons in 88-92ish are the new body style the 3/4, tons Burbs and Blazers are like the 81-87 trucks. Some of them have electric speedo clusters, which is what I have. Jay
