    CP4 to CP-ISB21S3 (revised CP3) change for 2021 6.7L Diesel Trucks -- Merged Threads

    Anyone noticing a loss of power and/or fuel mileage after the "fix" of going to the cp3.3 pump? I know the cp4 pump is supposed to have a higher pressure which should atomize fuel better to be able to create more power/fuel mileage. Stands to reason the cp3.3 would do less?
