TJ, I think I have a similar disconnect problem to what you found with yourn. What you said well they did that. I was gonna say hey put a pie tin on the drill bit and run a belt to increase the speed. But I forgot. See, they could only get it up to 25 or 35 mph and it seemed right. Also, before that, it got hooked up to a machine that said it read 2x speed so they fixed that. Meaning, the instrulment cluster works, the cable works. Except now that it's all installed it bounces between 20 and 80 mph. It smooths out some when I play good music.
