    2007 Yukon Denali RPm increase without pedal input

    Believe it or not, I've a similar issue with a 2002 Tahoe. For clarity, it uses a mechanical throttle cable, NOT an electronic throttle signal.

    2026 Tahoe-auto braking settings

    Long ago, owned a '94 Fleetwood LT1. Unlike Caprice/RoadMaster, it came with Acceleration Slip Regulation, aka Traction Control. (Side benefit of Traction Control is 4Channel ABS. Caprice/RoadMaster had 3Channel ABS; lacking Traction Control, 3Channel ABS was cheaper for GM then.) ANYWAY Even...

    First 5,000 miles

    CAFE fuel economy tests & scoring are designed & skewed to reward smaller engines and weaker axle gearing. CAFE results are NOT as reflective of real-world fuel consumption as, well, the real world. Case in point: Vast majority of NYC uber/lyft drivers who've used GM suvs with both 5.3L V8s AND...

    AFM/DoD Delete Advice Needed

    Part time / AFM lobes are slightly but meaningfully different from full time lobes, because AFM lifters are not the same as more reliable lifters. After about 2 decades, this is a 'known known'.

    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...

    AI is ruining your brain, and everyone else's, gottdamnt! 8th digit from the left! We read from left to right, remember? https://www.onallcylinders.com/2018/09/06/lmg-5-3l-engine-specs-performance-bore-stroke-cylinder-heads-cam-specs-more/ Your cam is Half@$$-able (although your cam does NOT...

    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...
