    Tips needed for rescaling MAF and TCV% Please

    Banks or S&B is what I would run. You won’t need to rescale the MAF. If you did run a larger intake. What I like to do is log the truck at idle and see what the MAF is reading, figure out the % difference from stock. Add that % to the entire MAF table in the tune.

    Fuel injector knock

    Yeah no. You can disconnect maf, map, and any other sensor you can think of. The truck will still run and have a low main rate. A low main rate means the truck is getting too much fuel. So how is this issue not fuel related?

    Fuel injector knock

    Then what is his problem? Also you can ask around everyone will tell you Lincoln diesel went to shit and they also give you the run around for warranty.

    158 MPH Max speed?

    If it says xx miles until max speed of xx mph that is an issue with the DEF system. It’s very common to have a communication issue at the DEF module. Also once you get that message, it is very hard to get it to go away since the implementation of “permanent” codes

    Increasing Rail Pressure to Control Idle Haze

    I wouldn’t risk it especially being in cold weather. When I was driving an LB7 it started to haze and went to not drivable within 100 miles. That was on factory injectors at 125,000 miles. I was only doing short trips at the time so I didn’t care if it left me stranded.

    Hydroboost trouble shooting?

    Is this for an LB7? I would just throw a hydroboost on it from an LML. It’s not throwing parts at it if it’s an upgrade ?

    What Lift Kit

    I know a lot of pullers that run rough country and never had issues. Normally I see people “hate” on a lift kit when either it’s not an actual lift kit, or when they buy a 4” and run it at 7” ?

    What will help my fog lights

    There are many LED bulbs now that put the chip in the correct location for headlights. Bulb facts on YouTube test a lot of different brands. Nineo on Amazon work really well.

    Can Heavy towing blow the engine?

    It depends how often you tow. Towing with added power decreases engine life. If you want to tow with a tune an EGT gauge and a 2020 oil cooler should be added. Also a good quality tune is a must.

    anyway to unlock efi live tune

    Maybe I’m not following correctly but if you have a 6 speed conversion, even if you have the tune file unlocked. If you’re using EFI live you will not be able to make changes to the 6th gear. 1-5 you can change
