    Does anyone have any experience with Ally claims, do they send an adjuster out to ensure no modifications have been done to the vehicle, and do they allow you to use a shop of your choosing for the repair work? Thanks

    Taking my 20 gmc in next week to get D&T. It’s 130 miles away and I have a service emissions system code up. I have 40 miles left before max of 55mph. (Code came up on way to work & had to drive it there & back) does anyone know what happens after 55? Is it 45 mph for 75 miles? Or something...

    Lower mileage L5P throwing a P24B0 code. Has anyone experienced this code? If so what is the fix? I’m seeing a lot on the DPF sensor being faulty. Thanks!

    Just curious if anyone smarter than me on here can tell me if the tank is forming condensation when it’s 26°F out during the day and 15°f at night. I have a 2018 L5p and I’m a freak about leaving the tank full when the truck is sitting and adding EDT winter treatment at every fill up in the...

    New to the forums and if I missed a previous post, about the same year model as my truck, then I apologize. First time diesel owner, drove a couple of my Dads trucks in the past but that's it. I noticed yesterday when I parked my truck a burning smell was present, and my wife even said something...

    I'm installing a VSE Fuel Saver system to replace my stock filter. During the process I noticed the fuel lines on both sides of the filter are really cheat material. Heck they're even wrapped with heat sheathing. Anyone replaced these lines for better quality tubing? Have any suggestion on...

    Hey guys! Did a Fuel filter today on my 17 L5P. Primed it and fired it up no issues. Moved on to replacing my high beams and after that I go to pull the truck out and it sounded like it was priming like it did after the filter change. About 15 seconds later it quieted up like it was primed and...

    I recently bought a 2017 l5p with 220k miles on it. I bought it from a dealership that changed the oil prior to me purchasing it but I want to change all fluids and filters. I want to service the transmission but i was told by my local dealership that if the transmission has never been serviced...

    2019 Chevy 2500 Had this issue for about 4 weeks now, random instances of P1089 code. Since then I replaced the fuel pressure sensor since some said it could be a faulty sensor. Still coding but only after a long deceleration period. I have a CT3 and have tried to data-log when it happens but...
  13. Wheels & Tires
    I have a 2019 Silverado 2500 Duramax. I want to fit 37x12.5 or ideally 37x13.5 on the stock wheels. I am thinking 5 inch lift with some sort of wheel spacers to fit. I wouldn’t like to trim the bumper but would like to remove the valence. Also do not mind trimming inner fender. Please let...

    I got a 2019 high country duramax that I wanna put some 20x10 -18 fuel twitch rims wrapped in 33x12.5 rubbers, what kind of lift do I need to have the wheels fit without making the truck look ridiculous? I tried the Kryptonite stage 3 leveling kit but found out the keys are clocked the same to...

    Just got a 2024 Chevy HC Duramax, I've put 300 miles on the truck. I got a notification that the emission system needed serviced, took the truck in and found out the EGR valve is bad. Anybody else had this problem? Just seems odd that the valve is bad considering the truck is basically brand new.

    So it’s been 6 months since I had the MotorOps SOTF tunes put on my truck (2018 L5P) and as temps by me drop into the 30s I am noticing my glow plug light never comes on anymore. Where it use to for a quick sec. Just wondering if anyone with the MotorOps tunes have the same thing. The light...

    My 2018 L5P has some sloppy steering and I’m looking to replace the box I have already checked the pitman arm and replaced the idler arm and I must have one of those box’s with the “bad” steering gear. Does anyone on here have any recommendations for aftermarket upgraded boxs or is my best bet...

    This might be a dumb question but if someone could help me out and tell me where the coolant in there surge tank falls to after it cools down it would help me out. Mine is currently sitting right at the Bottom of the arrows on the tank when cool and just below the filler neck when hot. I don’t...
