    Forged or Cast pistons

    100’s are enough for 500hp. You want to keep pulse short so the fuel stays inside the bowl.

    Forged or Cast pistons

    You’re going to want at least 200% injectors

    I have fingers pistons in The Limo and I don’t have the issues everyone is talking about 🤷‍♂️

    Duck the MANN or throw in the towel?

    I can confirm. Tune only L5P emissions intact hauls ass. Uses about half the def it did stock. Haven’t loaded it down heavy but it will pull any hill at speed.

    Forged or Cast pistons

    My LMM has mahle race cast, got them two months before Fingers came out with his. Haven’t broken one yet lol but I am on a single turbo and have 250% injectors. If I had a choice I would run Fingers.

    Lower valve cover leak with new gaskets & Bolts

    If I remember correctly the lower valve cover goes right over the second row from bottom bolts on the sides. Check to make sure it’s not hitting

    Not another compound turbo thread

    Been a while and forgot to update. I've only driven his truck for 5 minutes, but my initial impressions are all positive. With it being an 87 turbine, you do have that slight lag right off throttle like if you were slowing down for traffic and tipped back into throttle. Other than that, this...

    10 nuclear powered cargo ships would reduce as much emissions as every single car in the world if I remember correctly. But nah more money in messing with people who pull a cat off their car that runs e85 and still burns cleaner than it was factory

    We should look at cargo ships if we want to reduce emissions. Or hell just manufacturing things here, bring back more jobs and reduce emissions all in one. But what do I know 🤷‍♂️

    People are scared of everything and there’s probably more money scamming people with wind and solar

    But if the vehicle can burn cleaner and make more power, why isn’t that allowed.

    If the block has numbers on it which I would imagine they grabbed a block off the shelf. That engine is required to have emissions equipment

    GM didn’t want the EPA to come after them criminally for doing it 🤣

    twin tuning help needed

    How does it run on the stock tune with the maf adjusted? That should tell you if it’s injector related or tune related

    Sounds like a violation of your right to free travel to me.

    Unless they post a day ahead like they do with DUI checkpoints, they cannot stop you. They try and set up smog checkpoints in CA but they’re a “study” but you do not have to participate.

    I would think a Danville 63 would spool the same if not faster than a stock turbo 🤷‍♂️
