Topgunz - air to air upgrade

I tried searching this thread but no luck. What sort of fuel pressure are you guys running on the return style CJM kits? My fuel pressure gauge reads around 40psi at idle. Does it stay at a constant pressure? I did see a vacuum line leading to the fuel pressure regulator... I don't know how this stuff woorks

Disconnect the manifold line from the regulator, set pressure to 52 lbs, reconnect line. I have the same system.

Awesome thanks! The pressure regulator is literally installed under a bunch of coolant hoses that go to the throttle bodies.... wtf

Get rid of the coolant hoses going to the the throttle bodies while you're at it. No use heat soaking them.

I had read somewhere that these were not needed. Does it effect cold starts on a cold morning? I live in Colorado. One day it will be 80 degrees and the next it will be 20 degrees and starting to snow (yes I drive this car in snow.... less than 1" though, anything more and my front end will turn into a snow plow)

I live in Calgary; pretty much same weather, including the erratic weather patterns. Not an issue in the slightest.
