    Snap On vs. Autel

    I have both brands in my shop and the Snap-on tools come out of the drawer multiple times a day, while the Autel is maybe used once a week. Might be mostly personal preference on my part, but the usability of Snap-on is hard to beat. Autel does tend to have more features on some makes, but...

    weird fuel pressure issues

    Have you adjusted table B1012? That is an idle specific table.

    Yes, the plate comes off with the 4 Phillips screws. The picture 2004LB7 attached above shows correct install order. The spring fits into an opening in the valve cover, and the rubber diaphragm goes on top.

    You'll need to remove the plate to know for sure. The rubber flange and spring are the important parts here.

    Yes, and I should add, getting that tube wouldn't be a bad idea either. They might want to see all original parts to pass the visual inspection.

    This is the diaphragm I mentioned. Looks like you can get replacements. https://dansdieselperformance.com/i-30502205-pcv-valve-kit-lb7-lly-2001-2005-duramax.html

    Actually, that is nothing but a tube with a Y connection. The "Positive" part of the system is a little diaphragm on each valve cover that has a small spring and rubber valve built in. I ripped out the rubber and the spring when I rerouted mine. If the same mod was done to yours, the vacuum from...

    Newbie tuning

    All good advice above. I would add that Starlite diesel has an excellent manual for a very reasonable price. That's what I started with.

    LB7 Exhaust

    There are still a few stores that sell systems if you look hard enough. Personally, I think Flo-Pro is top notch. Here are a few stores that sell their sytems. https://dieseldiy.com/product-category/duramax-engines/2001-2007-duramax-6-6l-lb7-lly-lbz/...

    Efi live question motors lmm 07

    Like the other guys are saying, the replacement ECM will likely be flashed using GM's software at the shop when it's installed. Your Autocal should have the custom tunes on it. All you need to do is do a full flash when you get the truck back.

    Scripting Question?

    ^What he said.^ Just don't copy all differences. The ones to do are things like fuel rate, torque, main pulse, main timing, and boost. I would leave differences in pilot injection alone. And definitely fuel tank setting, gear ratios, etc

    anyway to unlock efi live tune

    I got it! I read out the module, modified the tune, and reflashed. So far she's working like a charm. And before anyone asks, I don't plan to post the file. I understand why DuramaxTuner locks the module in the first place, and it's to prevent their hard work from becoming essentially...

    Thanks a lot! That will save me the trouble of making my own.

    Correct. I've made very little change to the actual 6th gear tables though. It's mostly the other gears and TCC settings I change. Yes, that would be an option. I considered doing that, but never took the time. HPTuners has the 6th gear tables mapped, so I read my file with that and made...
