I recently replaced the entire fuel system in my 15’ LML duramax, including a Exergy sportsman CP3 pump. I had the truck previously turned by someone else and had planned on them making the tune revisions but they will not get back with me so I guess it’s my time to try out my newly acquired tuning information. Where should I begin with tuning for the new pump. The truck does run and idle but I have not attempted anything else.

Thank you!
