  Did Scott ever find the reason for this phenomena before anything else occurred?

we never figured it out.. the fuel pres was solid 39psi in the garage..
while in motion it never went below 34psi between first and second.... this told me all i needed to see.


anyway,, its a totally different engine now..... with one remaining issue we need to look at next week when he comes home.  we believe an exhaust valve is not seating all the way after doing our leak down test.

Fuel pressure should always maintain 39 PSI at WOT... That is what's important, if it's anything less you're running lean...
