    Lly bench flash with benchforce

    Did you ever pull hvac and radio fuses when trying to flash them in the truck? I’ve used bench force numerous times and never had an issue

    02 LB7 Crank no start

    That’s commanded regulator percent. What’s desired and actual fuel pressure?

    L5p tune has got me p0087 code

    If desired is going up but actual isn’t wouldn’t that indicate there’s a problem with the truck? A lot of times I see people with old batteries that refuse to replace them because the truck starts day to day but leaving the key on while flashing is enough to drain them and cause all kinds of...

    Fuel Mileage

    Kinda hard to believe an injector will clog up when there’s 30k psi flowing through them, anything making it through the filter will just get blasted to nothing.

    I have a built lmm I have the build list but honestly I just want someone who knows more than me to just kinda explain the setup its not normal☠️

    I think we can take it a couple steps back. I’m going to assume this is the only vehicle you’ve owned that’s been “built” When a vehicle is built there’s certain things you want it to do better, and there’s other things that will suffer. If you want to use it as a truck and tow, drag race...

    Coming Soon in Your Next Truck (?)

    For trucks I think hybrid is the only way. The F150 lightening is terrible. But their hybrid option with the ecoboost seems decent. Gm has the best electric for towing but still you’re very mile limited even a 20% increase in efficiency will still be laughable for towing range.

    Could definitely benefit from a better turbo. I would run a 72mm ball bearing with a 87 turbine. That would easily make 800hp and have good street manners. If you’re towing kinda changes things haha

    Mini max controller

    Mini max controller

    I’ve never had a problem with it pulling power on an LMM with traction control and stability control disabled. Now on LML it does turn back on after 45mph(something like that can’t remember the exact mph)even if it still shows it’s disabled

    L5P SOTF HPT vane position not working

    If you drive it around, it may fix itself.

    L5P SOTF HPT vane position not working

    I’m not 100% sure. Had a truck that would boost creep at idle and start dumping fuel into the exhaust. Ghost regen, EGR opening, or cat plugging. Not sure what was going on ?

    L5P SOTF HPT vane position not working

    They work when the truck feels like it ? I also found if map sensor isn’t working correctly the truck will run in some weird mode I haven’t figured out why yet.

    Limp mode No codes

    100% turbo limp. On my dad’s LMM with a 65mm the turbo was making more than commanded boost going up hill. Most tunes have the number of seconds until it checks itself maxed out that’s why you don’t have the issue driving around.

    L5P SOTF HPT vane position not working

    Yes and no lol 17-19 you can clear easily with most scan tools. 20+ is a pain in the ass and you’ll need a scan tool that can clear the DIC Edit. If you can’t clear a message on the dic, try clearing it with the engine off key on, and engine on. The DIC needs a signal from the ecm that...
