My truck is a 1999 k2500 ccsb with a 454. I just bought it this year and it’s been running really rich since I had it. I replaced the O2 sensors, replace all in injectors with a new fuel rail and fuel pressure regulator, new fuel filter, new fuel tank with a new fuel pump, then I replace the rotor, cap, and plugs with a msd kit and gapped the spark plugs at .45. New map sensor, new sensors on the throttle body, pcv valve.
For performance I block off the EGR route66 off eBay, it has some Gibson shorty headers and the Cats were already cut out.
