Re: 4000 PPM. I found out my cruise works fine over 75-80 mph. 65-70, it will come on for a little while then shut off. I can't remember if I connected it to my T56 or my PCM (it's been a few years). If it's the PCM, would I need to get it reprogrammed or make sure it's putting out 4000? Wouldn't 4000 PPM be 4000 if you were going 1 mph or 100 mph?
