    Need opinion — upcoming road trip

    AFM Disable is just tuning, no hardware changes. Delete involves hardware and should also involve tuning, although strictly speaking if it was already disabled previously more tuning may or may not be needed, depending on whether or not you choose to stay with or replace the cam. Fixed. 3.73 or...

    AFM/DoD Delete Advice Needed

    Please be more careful with conjectures, people ... disabling is NOT the same as deleting ... etc ... If you JUST ... ONLY disable Engine Half@$$ with a plug-in, or a tune that MERELY disables V4 mode, you only told the ecm to avoid using that feature, ever. If you haven't changed the cam specs...

    AFM/DoD Delete Advice Needed

    You can't have an LM7 if your engine has Engine Half@$$. LM7/L59/LM4/L33 are previous versions of the 5.3L you're concerned with. What's your VIN's 8th character? Settle it that way. LM7s are full time V8s. If your engine can Half@$$, it's not an LM7/L59/LM4/L33. H2O was already filtered for...

    AFM/DoD Delete Advice Needed

    I save SO much more @ CostCo, even though I had to change my outlook from a day or two ahead, to a month or even a season ahead in some cases. You don't NEED to, it's just a really good idea. It's a case of 'how much (more) money are you (comfort)able spending to improve the odds that nothing...

    AFM/DoD Delete Advice Needed

    The conversations SAY a lot, they just don't conclude anything. There are people who have NOT gotten cancer or emphysema or COPD from smoking a pack (or more) a day, but cigarettes are still carcinogens - they, among other things, increase the odds of getting cancer. By the same token, some...

    Oil Pressure - Am I paranoid?

    The Low Oil Pressure warning trigger threshold is a tune-able parameter in the ecm. Also, it's not 'simply 10psi': Here's a tuning suggestion: RpM: 000 . . . 512 . . . 1024 . . . 1536 . . . 2048 . . . 2560 . . . 3072 . . . 3584 . . . 4096 . . . 4608 . . . 5120 . . . 5632 & Up Min Psi tuned...

    New from Illinois

    Think SSVs are a better investment than PPVs, since they came with 3.42 vs the PPV's 3.08, which makes the SSV accelerate more competitively with the PPV, plus the 4x4 capability (duhr).

    DFM module for 2026

    If one is dumb enough to leave it plugged in when they visit the dealer, and the dealer and/or their mechs are not cool with you or the plug-in for whatever reason, then the dealer/mechanic might snitch. Shorter answer is to unplug it before visiting the dealer and lie about it if needed. For...

    AFM/DoD Delete Advice Needed

    So long as the bi-mode lifters behave, you can keep your original cam / lifters / pushrods / rockers (til something goes wrong, who knows when that'll be ...) Raise 'Enable Engine Half@$$ Coolant Temp' over 266F in the ecm, there y'go.

    Oil Pressure - Am I paranoid?

    That's how all motor oil works for everyone everywhere. However, this happens to 5w20 more quickly than 5w30. Back when I had a 2012 Y-XL, I went by the Oil Life Monitor, SORT OF. Mostly all highway miles (NOT NYC), change oil & filter by 25%, NEVER over 6000 miles. More highway than local...

    AFM/DoD Delete Advice Needed

    Disabling Engine Half@$$ in an otherwise GM OE tune, is basically telling the ecm DO NOT DO THAT, EVER ... but leaving the Half@$$-able cam & lifters in place, and leaving that cam's specs in place in the tune. If you install a 'real V8' cam in that engine (and 'real' lifters), the VE tables...

    AFM/DoD Delete Advice Needed

    Difference between a GM OE Engine Half@$$ cam, vs a GM OE simple V8 cam ... the part time lobes are not quite the same exact shape as the full time lobes, whereas the simple V8 cam ... you can guess the rest, yeah? The software differences are largely dictated by the two slightly different sets...

    AFM/DoD Delete Advice Needed

    LH8 / LH9 / LMF cam will do your 5.3L nice & easy, any tuner with cataracts can copypaste the LMF stuff into your tune, no talent required. Do not think a GM OE 6.0L cam (L76t/LY6/L96) or 6.2L cam (L92) would be an upgrade, even though I'd like to be wrong ...

    Oil Pressure - Am I paranoid?

    None of us will be able to assuage your fears as well as a mechanic, even though we're cheaper. Those don't look 'too' low, but I get it. Just before you're about to do an oil change, get your engine up to operating temp, then park it with the nose down (front tires at least 2ft under rear...

    Need opinion — upcoming road trip

    Don't know how a cam in a 5.3L will gain more than 20ftlb under 2500RpM, where most engines spend most of their time, which most dyno charts ignore completely. Hopefully I'm wrong, it'd be nice for a 5.3L to feel more like a 5.7L under 2500RpM. Regardless, any significant changes require tuning...

    6L80E compability?

    Euro 95 octane (RON) converts to American 90.5 octane (RON + MON) / 2 ... & that's your 'Regular', huh? Our regular is STILL merely 87 octane. I wonder if your '07 Denali-L92 spark timing maps are any different from American '07 Denali-L92 spark timing maps ...

    A/c causing my throttle to fluctuate and drop too low

    Some people go so far as to ask their tuner to raise the AC idles even further. My P/N AC ON idle is set @ 800RpM (same as any GM OE V8 with a stick shift). My R/D AC ON idle is set @ 700RpM (same as any GM OE PPV with a 4L60E). My AC OFF idles are set lower.

    6L80E compability?

    joe got it right. Technically, the 'vette 6L80E is installed longitudinally, like any other transmission with an 'L'. However, 'vette-specific 6L80Es can only bolt up to & mate directly onto the rear axle; NOT onto the engine. Bet you find a manual transmission that can be made to bolt up to...

    6L80E compability?

    Well, according to a guy I knew named Ermenegildo from Ensenada, the 4.3L V6 was an option in HD Silverados, and some of those 4.3L V6-HD Silverados also came with 6speed manual transmissions. Could swear the VIN for one of these Mexican HD Silverados with a 4.3L V6 & a 6speed manual is here on...
