smarty boost pressure question

626 Views 4 Replies 3 Participants Last post by  crf450x
I have a 04.5 2500. No mods except cold air intake. Just had all six injectors replaced. Before smarty I ran about 27lbs of boost with smarty jr on tow I can easily get it up to 35+. Is that normal and more importantly is that safe?

At what boost pressure should I become concerned? I know my stock maxed out about 26-27. Haven't really hammered the throttle so I don't know exactly what is not safe for the truck
