LB7 log

[Harshman]

This is a log of a LB7 that I recently bought. Something not right. Rail pressure is low under full throttle then goes up when I lift. Does not apear to be a stock tune. Don't know if it's that or a pump problem? Truck runs decent. Have not hooked to a trailer yet.
Fuel pressure is the line that starts low. Purple line up top is MAP. Other line that starts near the top is engine speed.
What you think?

Not enough info. Get us at least some mm3, PW, etc so we can tell how hard its running

This CTS3 doesn't give me that. Will have to use EFI live. Will try to do that tomorrow.
