I have heard 30 psi is the safe limit.

32psi. Some go over, but your pushing it once you do.

A buddy and I just put Edge Juice w/Attitudes on our trucks, his '07 Classic mine '06. Took the trucks out for a spin after words I was seeing boost levels from 24-27 his were more like 34-37. Not Kiddin! It has been about 2 weeks now and the numbers are the same for both.
