I see that UPR uses check valves in their catch can set up for the 10-14 SHO. They give a option of a high flow PCV valve. Is this advised to install for best results? Is itjust a hogged out connector? Or just stick with the factory PCV valve. Thanks for all your input. I
I stuck with the factory PCV, it works great with UPR's catch can.
I upgraded my check valve to the billet pro series check valve after talking with one of UPR's reps. I asked about the difference in check valves and he said the check valve that comes with the kit works great but since I make multiple trips to the track and drive the car so hard and often he recommended I upgrade due to the extened operating time under WOT and boost pressure being over 16psi. You simply swap it out with the original check valve and its roughly $40.
