Looking for a diagram of boost hose routing to and from solenoid in front of sled.
Thanks
 
Had my sled apart for a while.
Dont remember wich hose goes to intake and which one goes to blow off valve from the solenoid up front.

Had two lines hoses crossed and by studying the parts manual, I figured it out.
 
I had seen this online but did not help with the actual routing of hoses.
The ABV solenoid had the boost line and blow off valve crossed.
This created a big issue.
The boost would only go to 9 psi and the fuel pressure would go lean due to the rising rate pressure with boost.
It created a very lean condition.
The conditions of what was happening and looking at the parts diagram I figured out the solenoid valve was not delivering enough boost to the fuel pressure regulator.
All is good now.
