I had my fuel injectors cleaned and changed my oil (still syntec 10-30) and my hot idle pressure is now 18-20lbs. Im guessing due to how much smoother the motor runs.. Im going to order one of those valves once I get around to it, let me know how it is if you get one first 
I also run synthetic and my injectors have been cleaned and balanced also. NP i'll let you know what i notice when i do it in the spring. I asked for it for my birthday which is the end of april. so lol i'll probably post up that day.
