    Please help…Lml with sdp compound turbo

    You could just wire it up to a heated steering wheel 🤷🏻‍♂️

    Lml no start after regulator removal

    There’s a harness in front of the motor that if disconnected it won’t close the regulator. I don’t remember exactly where I’d have to go check. Doesn’t hurt to make sure because I missed it once 🤣

    1470hp on a stock engine...

    I’d be curious to see the rpm they’re running it at. We know 1200ft lbs is enough to bend rods under 2500 rpm but what about at 4000 rpm 🤷🏻‍♂️

    anyway to unlock efi live tune

    IIRC it’s an issue with EFI live. You have to bench flash the ecm and that’ll fix the issue. But I could be wrong. I ran across a couple LLY’s that had that issue.

    LB7: CP3 mount that fits a ATS Duel CP3 Pulley

    I had that happen to my ppe mount. I just welded it up and added a brace to it, triangulated. Has last another 50k miles no problem

    Hyperflash turn signals

    I believe there are certain trucks for like construction or police that have leds, you’d have to find one and get the vin number and have a dealer flash the bcm with their vin. Not sure if that’ll work on 2011+ but 07.5-10 wasn’t a problem

    Best rotors

    On my dads 18 stock wheels, it warped the rotors just slowing down after hot lapping it at the track.

    Best rotors

    Flush the brake fluid with Castrol SRF racing brake fluid. If they’re warping rotors their brake fluid is probably close to failure.

    650hp

    I missed that this was for a LB7 🤣 you can get close to 600 with injectors and up pipes. So ignore my turbo recommendation. Who says you can’t pull with sac injectors?

    Best rotors

    Stop tech slotted rotors seem to work well. Do not use a drilled rotor.

    L5P programming injector trims with Hp tuners ecm

    Number 3 and 5. I know the MDI II worked to do the anti theft relearn so I would assume it should work to do the trim codes, but also a snap on should have worked as well 🤷🏻‍♂️

    L5P programming injector trims with Hp tuners ecm

    Only problem now is that when they tried to do it with the snap on it changed the injector codes to all zeros and the truck has a CEL on

    L5P programming injector trims with Hp tuners ecm

    It's in Loomis Ca, the shop can have someone come with an MDI but I wanted to see if any knew for sure that would fix it. I could plug into my dad's truck and double check but it's raining in CA and I might melt :) and also, I don't want to screw his up if for some reason the hp tuners ecm...

    L5P programming injector trims with Hp tuners ecm

    Has anyone successfully programmed injector trim codes on a L5P with an Hp tuners ecm? I have a friend's truck that was taken to a shop for a misfire and an injector was replaced and a snap on used to change the trim codes, but they all went to zeros and now will not allow it to be programmed...

    Twins with Twins, Anyone?

    You guys are actually reusing parts? Usually when I take something apart it’s been blown to pieces 🤣

    Renewable diesel?

    You didn’t get better mileage with a 50/50 blend? I would drive to sac all the time to get a 55 gallon drum of propel 🤣

    Renewable diesel?

    I noticed on normal trucks it’s worse mpg and performance. But anything with big injectors it’s very apparent.

    Lmm in lbz

    Well yes that would be easier but I bought 250% LBZ injectors instead of getting LMM
