The R1 is decent Diverter valve but isn't adjustable nor does it vent to atmosphere like the Forge Splitter valve does.I just replace yesterday my Forge 007 for a APR R1 and I'm really happy. just intall it to divert back to the intake like the stock. My forge was due to a rebuild kit and was sticky and surging like hell from 20 psi to 15 back and forth. now i spike to 21 and settle at 17-18. Im running APR 93.
