I just want to give you guys a heads up on this issue that I had. After having my Horsepower LLC brake booster and proportioning valve installed for about 300 miles I noticed the front of the proportioning valve leaking. I contacted Dan at HP LLC and he said that they had some problems with some of the pro valves leaking. I just wanted to inform anyone that has this kit to keep an eye on their pro valve for leaks. Dan was happy to send me the replacement part for the pro valve and it was easy to replace and hasn't leaked since replaced. I included some pictures of the part and where it was leaking from. Hope this helps and don't forget to rebleed your brakes after the part is replaced.
