    Lift pump and fuel filter delete

    I have an older FASS 95 unit. It has been rock solid but about a couple years ago I started getting pressure fluxuations. I know this because I put a low pressure switch in the filter delete housing kit that I also got. My pressure switch was set for about 4 psi. At idle the pressure switch...

    Getting back on the horse again

    I feel your pain. My LMM has all the work done to be super reliable. Just turned 200K on it and hold it back mostly for trips. I usually get it out once a week to take to work just to keep things in good working order. Could not think of ever selling it. Super clean, no rust (had both rear...

    Trailer Brakes Too Weak

    Very good! I went back and checked my reference charts for voltage drop and current carrying capabilities and 10 gauge would have put you at 17 amps for each brake pulling a 4 amp load but at that distance and everything else considered 8 would have been the best option. Most certainly...

    Bare minimum of upgrade parts needed for longevity for a sub 700hp build.

    I have not done much for mods. I did away with the stock fuel filter and added a FASS 95 lift pump. Did a Gearbox Z plus tuner that added 70HP and then recently did a S&B 62 gallon fuel tank. The tuner also did away with some of the EPA friendly stuff. Changed all fluids over to synthetic...

    Bare minimum of upgrade parts needed for longevity for a sub 700hp build.

    Exactly the point I was going to make. It is one thing to crank up the tune to make more power but that is not the goal when pulling a substantial load. I would say pistons are about the weakest link here. I did a 70 hp tune on my LMM and is about the best for both worlds IMO. Helps a bit...

    PJ Trailers

    Powder coat like anything else does not last long if the metal is not properly cleaned and prepped. Truth be told I don't see most trailers being prepped at all before being powder coated or painted. If powder coating is an option on ordering a trailer I would always stick with the base black...

    Hot Shot Secret vs Optilube

    As stated above the injection pump for the L5P is the Denso HP4. Before the L5P (your 6.6 2022 Duramax) came on the seen there was the LML series of Duramax. Those used the Bosch CP4 for the injection pump. This was a two piston design that would have worked fine in the old days before the...

    Hot Shot Secret vs Optilube

    I completely agree. About the only time I would consider using an additive is if I had a Duramax with a CP4. Honestly it is not a mater of if but when the CP4 will grenade itself and you only move the clock up with any tuning. You can thank the ultra low sulfer fuels for that. Certainly not...

    Module confusion and issues on my 2008 LMM

    Yeah, nothing is more frustrating that an intermittent issue like that. I have seen quite a few videos on Youtube where people just gave up and just traded the truck in at the dealer. Problem for me is I love my 08 LMM. Got 200k on the odometer and the old girl still looks pristine. If...

    Module confusion and issues on my 2008 LMM

    Well I hope this is the final nail in the coffin on this matter. My problem is completely gone. Although I did not find a smoking gun my problem definitely was in the shielding for the antenna coax. Taking an issue like this to a dealer would have cost thousands and probably not correct the...

    Blockheater tripping gfci

    I will say my LMM heater routing had the power cord rubbing up on some support structure. Just enough to expose a small bit of wires. Wrapped it in electrical tape took care of that. I would suggest just looking at the routing of you power cord and look for something rubbing against it...

    random discharge of batteries

    I'm with ya. Grounds are a problem for GM. Kinda slapped together and little of any protection from the elements. My dad was an electrician so I got the heavy gage crimps in my shop. One ground I think is a must is between the engine block and the engine firewall. There is a ground there...

    random discharge of batteries

    A quick check of the batteries is after driving the truck go in and disconnect both batteries. Let them stabilize for about 10 minutes and write down the voltage on both. Let them sit for a day and go back and check voltages again. If you got a battery dropping voltage on you then you know...

    Module confusion and issues on my 2008 LMM

    Well, everyone I have not communicated much on this issue for a bit simply because it has not occured since I wired this up like a lab experiment. With diesel prices the way they are honestly the truck has not been used much. I did make a run to St Louis and back to move my son there and about...

    Rotella T6

    I know for some time the Shell Rotella T6 was damn hard to come by. When you could find it some were asking about $100 for a gallon jug. Stopped by Wally World on the way home from work to pick up a couple of new batteries for my LMM and happened to walk by the oil section. There to my...
