Exhaust back pressure limit before studs
Hey guys, got a quick question.
I currently run the HD300 tune on my truck. As we all know exhaust back pressure kills head gaskets. Im running my low boost fuel setting at 3. Stock valve train And stock internal parts. What is the most I want to be seeing of exhaust back pressure read off a mini maxx. I know barometric pressure plays along in the equation, but what the programmer reads, what's the safest. I am currently seeing only 65psi of exhaust back pressure that my mini maxx is telling me.
Later on I'm doing studs and valvetrain with the cab on and am going to make a thread of how to do it. I just want to know about the ebp.
