    Why aren't L5P heads on older gen trucks?

    Ya I called BS on them spooling 472 (or 476 I don’t recall) until I seen one do it. Of course 4 set of pistons later that guy was done with messing with the L5Ps.

    Why aren't L5P heads on older gen trucks?

    Yeah I guess I can see where that would make it a little less feasible. I wonder if Fleece or anyone has ever looked at making older head that bolts on but has the flow of a L5P. You wouldn't think it would be all that hard since the design is pretty much there minus making so it "bolts" on...

    Why aren't L5P heads on older gen trucks?

    Another thread got me thinking about this again. My understanding is one reason the L5P spool so well is because of the heads. I really figured by now people would be machining L5P heads or have their own castings with an L5P style ports. Is there really just not that much of an improvement in...

    Injector Limit for Cast Oval Bowl Pistons???

    That's exactly where my tune/truck is right now and it just hazes after limiting the fuel down low. I run a 12mm stroker. Truck feels lazy to me when it's tuned to run "cleaner". I think a lot that is the converter that's just to tight, but my transbuilder says it's the turbo...

    Cheapo Amazon LED headlight bulbs

    I just put some Lasfit LED bulbs in my fogs after modding them to have a cutoff. ( I made a thread on it I think) They've been pretty good. I see tons of guys recommending them on Facebook for the 2020 and up trucks that still have Helogen bulbs. I don't know if they're really that good or if...

    Anyone help with trouble shooting 6.6L gasser hard start?

    No the new trucks don't run them. Just a flap that yoi stick the nozzle in. Ford does it too. I'm assuming it's because they got tired of vehicles coming to the dealership with check engine lights because people didn't put the fuel cap on all the way.

    I think that was for the media. There's videos that people took of him going at it a bit harder.

    Anyone help with trouble shooting 6.6L gasser hard start?

    I went ahead just did the fuel pump since it obviously wasn't happy. I'm not sure that the hard star issue is resolved. It only really showed its head when I shut the vehicle off for certain amount of time. Start and stop it just fine but something about getting around that 2 hour mark we're...

    Anyone help with trouble shooting 6.6L gasser hard start?

    That fuel pressure sensor location is bad. Look like it is right on top the fuel tank. It let me once I let the truck sit over night. My truck runs most of the day so it’s hard for me to get a true “cold idle” I guess.

    Competition Diesel gone

    I never did care for comp D much. Too much nonsense for me. It’s sad to see it go though. I do find it funny that Facebook groups for sites like that don’t take off. I mean, even our own see’s very little activity.

    That Operator was sure doing everything he could to save those cars. He could’ve ran through those things like tin cans if he wanted. As much as everybody loves California’s weather…fuck fire season. I had 2 close calls while living there 02-07. Fuck Californians and they’re open space laws...

    Anyone help with trouble shooting 6.6L gasser hard start?

    Well I guess the engine being cold is very specific. After trying it after the truck sat over night it worked fine. After the truck died it was still reading 30psi. I can't afind anything about a low pressure fuel sensor. There is a high pressure in the rail and a tank pressure(emissions...

    December '24 Chat -- Merry Christmas, Ya Filthy Animals!

    That’s pretty wild. We see that a lot in the construction industry. Most of the keys are universal so it’s not uncommon to have people mess with machines. What’s worse is now they’re going to almost push button start on everything so we’ve had a lot of kids take the machines too. For whatever...

    Anyone help with trouble shooting 6.6L gasser hard start?

    Looking more like the fuel pump, but my damn scanner won’t depressurized the fuel system like it should. Duty cycle is 90% at idle. Almost 11amps and 7000rpms. Can’t find a fuse/relay labeled for the fuel pump to try that method. Can someone point me in the right direction?

    2027 more emissions....

    Yep, just saw this video. So let me get this right we need direct injection to reduce carbon dioxide, but it increases nox and particulates. So now we need particular filters on gassers..... F***me Source: https://youtu.be/k1yNzrySHMY?si=9Y2MFKOYW3j0QbZU

    Anybody drag race with an lbz??

    Are you running a lift pump? 4x4 right? Looks like your Tbars are al little high. CVs should be flat.

    2024 Duramax issues?

    The rear suspension is really soft on my used 2022. From what I saw, they’ve done some weird stuff and had additional top overloads on certain trucks. I haven’t really figured out what package it’s part of. My truck didn’t come up with an additional top overload. I ended up adding a road active...
