    What’s the best conversion kit for the money. I’ve got a bud that has this CP4 and want me to convert it over to the CP3. I don’t know which one is the best for the money cause I have the CP3 already in my 09. Can y’all help a brother out? Also I’ll need to get a replacement bleeder for the...

    Rebuild????

    Get ready to spend some money! Getting the tuner for all that is not easy and now its expensive as hell. I deleted mine back when I had 3,500 miles on it. I bought mine brand new in 09. I seen pics of the inside of a duramax motor that had an EGR system its whole life. I refused to let my motor...

    I’m looking into some new injectors and a CP3. I was told to go with Marine injectors. What’s the best way to go on that issue?

    Rebuild????

    He just told me he has a FASS. I know I don’t want that for sure but I was told I didn’t have to worry about it with my 09 LMM

    Rebuild????

    I will shoot him a message and ask which one he got. I really don’t have and fuel issues tho. When I hit the throttle the truck is gone like a rocket. But I nervous when I see that mileage getting up there around 200,000.

    Rebuild????

    I run a three gauge Pillar set. Boost, Exhaust temp and trans temp. I think I will change the trans to oil pressure. I also have some tuner questions. Can you answer them or recommend someone here that wouldn’t mind talking to an old guy?

    Which pump is best bang for buck? It seems y’all give pretty good advice so I’ll take any advice pretty highly.

    Superchips

    I am currently using a SuperChips tuner. It is also outlawed now and they will not update the tuner or have anything to do with it at all. I can’t say I am not pleased with it because whatever they did to get this tuner outlawed……sure made my truck unstoppable! I have never seen taillights from...

    Rebuild????

    I need to update my profile here. It’s bee quite awhile since posting and I’ve done quite a bit of work on this truck. I bought it new in 09 and I have had a couple issues but overall it has been a great truck.

    Rebuild????

    CP3? I don’t know all the tech talk y’all use on here. The oil pressure has always concerned me. When cold it is up but after warming up it has always dropped lower than what I considered to be okay but was told on here that it was fine. What’s the low limit considered to be?

    Rebuild????

    I have right at 200,000 on my LMM. When is it a good time for a rebuild? OR, what’s a good mileage for a rebuild. I took the EGR and DPF off around 3,500 miles and done a few things along the way. SuperChips tuned, Injectors, Cold air and a stage three turbo, I gutted the CAT Converter so I’m...
