Steve, I recently had an insert built for my cab and I disconnected the fans so it would fit.
Out of laziness, I took my time getting them set up again. It was a big mistake as I had some fluctuation issues.
How many lbs of beads do you have?
I have 4 in mine and with the hydra I almost never have to charge them. (only once since August).
Perhaps you have a leak?
I recently put weather stripping around my door not because I had a leak but I was in the hardware store and it was $3.
It feels like the door seals tighter but I dont know if its working for sure.
If you have a leak, HCM beads will be just as much of a headache as your heartfelt beads.
You can also recharge your heartfelt beads the same way you would HCM beads, if that makes it easier for you.
Hope this helps, Bud
