    What fluid for transmission.

    IIRC that was for stock clutches. Any Dex III for aftermarket. I ran valvoline dex/merc and he never told me i was an idiot so ??‍♂️

    Compound p/r understanding

    Ppe boost valve just dumps pressure out the fitting and it has a smaller opening. Do a regulator.

    Timbrens, who tows with them?

    About 10% less than great ? I ran a one way valve to a 1 gallon air tank and a return line with a needle valve almost all the way closed.

    Timbrens, who tows with them?

    I tried this on my dad’s truck, works really well. But not great

    Looking for guidance and backup support before flashing LB7 (EFILive / LDS tunes / DSP5 / emissions)

    Pull hvac and radio fuse or what terminal do you move under the dash to make it bypass the truck? Theres a thread somewhere about it.

    VGT turbos

    Duramax turbos are not going to work for your project. Just get some VS racing ball bearing turbos and don’t bother with VGT

    Alright Allison techies, flare for 1-2 and 2-3. Everything else golden

    Time for a trans rebuild

    LMM: Tps and rpm signal

    TPS I got right off the pedal because I wasn’t doing rpm just WOT switch.

    Timbrens, who tows with them?

    Not to answer for James but airbags make it incredibly difficult to dampen especially constantly varying loads. The only way to make it work how he would want would be electric controlled shocks like in the teslas. I feel like most people don’t realize how much helper bags destroy ride quality...

    Timbrens, who tows with them?

    Just do airbags and add a 1 gallon air tank inline. Use a one way valve going to the air tank with a return line controlled by a valve. Allow the slightest bit of air to return back to the bags. Gets rid of all of the bounce and doesn’t pogo stick. Or just run timbrens ? but do we ever do...

    Crank no start white smoke when starting

    Would it still spin the CP3?

    DK pistons, junk or good?

    I’m curious to try it on my next build. If I end up with piston slap ??‍♂️ can’t be any worse than my hone job I did at home and slapped pistons back in after cracking some ?

    DK pistons, junk or good?

    The theory is you’re able to run a tighter clearance, even with a cast piston. The coating will only wear out where clearance is needed.

    DK pistons, junk or good?

    The line 2 line coating wears out where clearance is needed. It’s used in racing applications so not sure how it would hold up for a daily driver.

    DK pistons, junk or good?

    I’d be curious about using forged pistons and having them coated by Line 2 Line coating to close up the PTW clearance

    DK pistons, junk or good?

    01-05 duramax didn’t have piston issues. You could take a set of 300,000 mile pistons delip them and run them at 800hp and get good life out of them. People would run 3300 pulse and weren’t concerned about them. In 06 everything changed, stock trucks were cracking pistons. Sure you can make sure...

    ^ what they said. We already have enough problems with pistons, why not go with something better like the motorsports piston(which I would go with fingers just because). Anything else is a gamble.

    LLY ECM Help.

    IIRC only read balance rates by themselves not any other PIDs

    Did I just destroy my LBZ? (aka What the h*** was I thinking)

    Did you disconnect the glow plugs and grid heater before doing that?
