thats a little high for the vp in my opinion. 17 is a good number at idle.

That's a good safe pressure. Your truck will run good when you get those sticks. I used to have that exact same setup. It ran good!!!

Mine is adjusted running around 20 to 22. It kinda likes to change psi at idle between 20 through 22
