    Stroker vs dual cp3 question

    Okay, I know there are tons of discussions about this topic already. But I have been reading old cummins forums from back like 2015ish where guys were saying that stroker cp3's were laggier than a stock pump/dual cp3 set-up, is that even a thing? Or if so, has better tuning just eliminated it as...

    low pressure fuel leak got me stumped

    During the 8ish years of owning this truck I have fixed multiple fuel leaks, both high and low pressure. I'm 99% sure this one is low pressure since pulling the regulator on the cp3 gives me nothing, also the truck starts fine if I let the lift pump run for 6-8 seconds before I crank it. If I...

    New or Re-Build Steering Box

    My steering box is leaking. It has 287,000 miles on it, should I get a re-build kit for mine and replace all the seals? Or am I better off to just get a parts store replacement with a lifetime warranty. I have searched and searched and there dosent seem to be a good solution. Some even say...

    Is this Normal?

    So I have noticed this for a long time and just assumed it was normal, now I'm not so sure. But when I'm accelerating hard on my bigger tunes and I hit a little bump like say where road meets bridge or something like that, anything that's enough to bounce the truck a little, the truck stops...

    Finally got the truck running, help

    Well my truck is finally running again, but it's knocking pretty loud on the passenger side, something is definitely not right. I sent videos to DHD and they said they think it's injectors, so we checked the balance rates and they looked good, now I'm just waiting to hear back from them again...

    Need New Starter

    I searched and could not find any starter upgrade recommendations, I seen the one Dmaxstore offers for around $225. Does anyone have any experience with an aftermarket one or should I just go back with oem? My truck is going back together this week and mine is shot.

    Tuned LML Defuels too hard

    My cousin has a 2016 LML with a sportsman cp3 conversion, Airdog, and Marks tunes. The truck runs great except it defuels so hard and long before each shift you will almost hit your head on the windshield. No codes, I bet it cuts fuel for a full 1.5 - 2 seconds between shifts, no exaggeration...

    Exergy Fuel Treatment

    I have searched multiple times and found very little information on the Exergy fuel treatment. I recently bought some to try since I know Exergy is at the top of their game when it comes to fueling parts. Does anyone know anything about it or has anyone else tried it yet?

    Dmaxstore Connecting Rods

    I have never been able find any information on the Dmaxstore Performance connecting rods rated to safely handle 550-700 hp.
