low oil pressure is really going to limit how well the injector can peform.
that could be one reason you have low boost.
i would definately clean everything up and run it to attempt to see where its leaking from.
if it is the gasket leaking id start their, then ipr and icp.
also make sure you are not low on oil, these trucks run like crap with low oil
forgot to mention p12111 is injection pressure above/below desired.
so i you have to high or too low of oil pressure it can set the light.
