My truck was converted before I got it, but I had a leak in that little valve that looks like a plumping part 90-degree with the probe that goes to the discharge tube to moderate expansion (expansion valve? not sure).

What needs to be recalibrated? Is there any way to tell if that was done when they did the original conversion? Or could I just have a shop "adjust" my current one somehow?

Doesn't sounds like I -must- do anything, but that you got better results with a reconfig, so am curious.
