Do they polish the inside of the bowl to give the water less to grab on to while it is rushing through? I also heard they will do something magical to the impeller on a Jacuzzi, what exactly do they do? Someone told me they reshape it, to what? I keep hearing a lot about these guys and i am wondering if this stuff anything the common man can do They will thin the vanes in the bowl,do some work on the impeller.for basics,But there is alot more he can do for set ups.I had the basics done and i kept the same speed just 400 rpm lower.
If it is the wj jacuzzi he can make it go pretty good i am not quite sure what they do to it(been a while since i owned a jet)but they work good
