Why convert your LML's Fuel System from a CP4 to a CP3

  • The stock CP4 is only capable of supporting up to ~500rwhp. A stock CP3 is capable of supporting 600+ rwhp in conjuction with the piezoelectric injectors. The reliable and proven PowerFlo 750 is capable of supporting nearly 850+ rwhp.
  • 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 piezoelectric injectors. Since its introduction it has proven to be less reliable and less capable than the CP3 used in previous duramax platforms.
