i had intermittent problems with my 76mm C&L. got a 80mm ProM and love it. haven't had any problems. As far as what the tuner is saying, it's probably like Grady was saying, they probably won't make a profit on it, so they don't want to do it.
might want to look into another tuning option. I know the PMS is expensive, but rick anderson gives you a base tune to work with when you buy it.
