Default really sluggish

ok so the day i ordered my 100 horse pods my truck started to run a little sluggish. almost like its not getting enough fuel. i can barely pull 700 on egts. i put the injectors in and it definately improved it but it still doesnt run as good as before. my shut off solenoid went out and i was wondering if it could possibly be the rubber pieces blocking fuel.

For some reason not many see noticeable problems from disintegrated solenoids. It's odd since nobody's ever explained where the debris go... I'd imagine that a few are unlucky enough to have the rubber end up in a delivery valve or injector. I don't really know where else it would end up. Maybe in the rotor itself or in the spill port under the collar, but I find it hard to believe that something could stay in a itty bitty 20,000 PSI passage.

Fuel filter?

I agree Begle, its odd.... But it happens...

Fuel filter is a good check. How about fuel pressure also...
