Lean at WOT issue

[SoBeeYou]

I found my Intercooler clamps when removed were a bit messed up and possibly pinched the hose. I am replacing those. I also thought I would get the injectors tested, they came back good but were clogged.

They said after cleaning them they produced 5 mL more in the same amount of time as before. Hopefully this helps out along with new clamps.

Sorry to bumb an old thread.. but did you ever figure out your issue. Currently having the same issue with me being 14.7afr at wot. 8lb of boost

Probably boost leak

I did a boost leak test. Holds fine at 25lb and drops 1psi per second.

Fuel pressure at idle was at 41psi connected and 55psi disconnected from intakemanifold.

Fuel pressure sounds too low. And if it is losing 1 psi of boost per second, that doesn't sound like it's holding fine...
