Governor / Speed limiter 2000 GMC 3500 5.7
I tried the search function but didn't see what I was looking for, maybe you can help me out? I have a 2000 GMC Savanna 3500 with a Thomas Minotaur 29 passenger body. 5.7L gas engine. It won't go more than 60 or 65 mph. Is the speed limited in the ecm where I could over ride it with a programmer, or is it an external governor of some sort?
