This is my first cat rebuild. Any advice would be helpful.
Rebuilding a 3406e 6TS original (435hp), with IPD kit. Stage 3 head, 5ek cam, and bigger turbo, has 601 program, with a 9850 injector code at present. It has 8501 injectors at present. Had 3 injectors firing weak so I’m Going to put new injectors in and was thinking of going with the 8502 match flow set. Any thoughts or advice would be helpful.
Advantages or disadvantages?
