Is there any tuning capabilities that can help the CP4?
I'm not sure if the computer can lower the PSI on the pump, is there anything that can be done from a tech standpoint?
I'm installing a FASS lift pump in hopes of helping the CP4 but may have to pull the trigger on a CP3 swap.
The 2K-3K price tag is a bit much.
I run high quality diesel and use a lubricity additive.
