Convert your LML’s Fuel System from a CP4 to a CP3

The stock CP4 is only capable of supporting up to ~500rwhp and 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, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms. A CP3K is capable of supporting 600+ rwhp in conjunction with the piezoelectric injectors. The reliable and proven PowerFlo 750 is capable of supporting nearly 850+ rwhp.
