Dave - thank you for the actual numbers - that is what I was looking for!
What is a high boost #? Under normal stock circumstances I don't think I could ever hit a dangerous level, but when things break on the vehicle, something might cause it to go way up. One of those things that if for some unknown reason while out on the road if boost starts running higher than normal, I will be wanting to know if I can drive it home or to the nearest shop.
