*nods* makes sence. I was running on the assumption that the biggest restriction was the hose and barbs. Is the restriction in the quickswitch the hoses and barbs? How about some of the competing 4 ways? I have the CFM ratings of the electronic valves I bought. the passages inside them seem to be larger than the holes in my 10/32 barbs..

As for the rock, I called and spoke to craig last week. I have decided I'm not goign to try to fix it myself ;-) The safety relief valve is activating way to low.

ps. I'm the guy from the IAO who picked up craigs blazer and proceeded to shortstroke it. :-) I was wearing a blue jersey with a Bunkerhard Logo on the front.
