You got to fix the leaking injectors or determine how bad they leak. The only thing the gas pedal controls is air. the ecu controls fuel. If anything is out of whack the ecu's calculations are going to be wrong.
I was also thinking timing, but again you say it spot on. Spot on what is spot on stock 20deg or KAT 15-13deg? IDK because you didn't tell me. If you don't have a cali or OBDII ecu, codes usually get stored (no cell) unless it a huge problem.
