I have been told that with gas motors that have 7psi or more of boost require timing changes. So my question is, If i am acheiving 15psi of boost on my 6.9 do i need to make a timing change?
I ask this because i think i went thru another set of headgaskets. Yes it is studed, and the head and block surfaces have been checked.
Anyone have an idea as to how much boost these motors can handle?
I am really getting sick of doing head gaskets every 2 months.
