    10 lb spring but only 5-7 psi? Something isn't spooling up correctly...

    Okay...I KNOW I've posted this twice already...but here goes again. If you have the stock 60E (I don't know because that info is not visible) it will not hold 10 or more psi. but it's been proven over and over again...
