Hi Bob,
I did do mag check while flying and all tested out okay. I do have JPI and three cylinders were running a little cooler then they should have. #2 290 F, #5 270F and #6 270 to 280F. All others about 320 to 340F. As such, I thought it was due to partial blocked injectors, but they turned out to be okay. Also when we ran flow check on ground,with low boost electric pump and flow into cups, it appeared all injectors flow were equal. I did not attempt to run low boost while flying. Should have but didn't think of it at the time. I agree that it is either the upper deck controller or fuel pump. However, also can be a hung fuel relief valve. Dirt or something may be holding it open more than it should be. We will do pressure test tomorrow night. I'll keep you posted what we find.
Cheers
Jerry
