Description

S&S Diesel CP4 to CP3 Conversion Kit with Re-Calibrated Pump.
For 2011, 2012, 2013, 2014, 2015, 2016 GM 6.6L Duramax, LML.
CP3 is already re-calibrated to match the LML stock CP4 fuel curve. Kit is designed to replace the less reliable CP4.

The CP4 was introduced as a cost reduction to the LML platform since a smaller amount of fuel is required when running the more efficient injectors. Since its introduction it has proven to be less reliable than the CP3 used in previous Duramax platforms.

  • NEW Bosch OEM CP3
  • No Tuning Required
  • CP3 is already re-calibrated to match the LML stock CP4 fuel curve
  • Kit is designed to replace the less reliable CP4 that comes stock on the LML
