FYI, that's actually on the C7 Corvette, not on the Gen6 Camaro. The latter has 100% throttle opening from 0 RPM available. Graph attached from my SS 1LE's stock mapping. ZL1 may be different, I don't have a ZL1 stock file.

lugging is lugging. it applies to more than just the ltx. big truck motors for example - they make peak torque near 2k ft lbs at 1100 rpm. guess what happens when they’re driven and loaded frequently at those rpms. yes, they suffer egr problems (if applicable) and deposit build ups. there’s more to an engine than numbers. some of you get it, but it appears most don’t. as i said before, we can explain it but we can’t understand it for you.

Only 3k rpm? Lol, my '90 Miata was turning over 4k at 70 mph.

Don't fabricate falsehoods. I didn't say that.

1>4 skip is active as low as 16 mph and the blocker retracts around 20 mph in the SS. Best mpg tends to be lower rpms/higher loads. EE vids do a good job explaining it, and I agree it's about what an auto does as the OEM is trying to maximize fuel economy, at least if the trans is in standard mode vs a performance mode that may discard fuel economy entirely. https://youtu.be/iNspNdVkslA The gearing in the SS and ZLE tranny is different, it's more like a 5 speed with a 2nd overdrive gear while the ZLE is more like a normal 6 speed manual. SS and Zl1 have about .75:1 and .5:1 5th and 6th while ZLE 6th is about .75, if I remember right. Anyways, in my SS I can shift into 5th as low as about 38 mph so that would be the same for 6th in the ZLE. You could easily do a 1>6 shift, lol... |

Lugging

Shifting to 6th at 50 mph isn't driving for "fun" or because I "feel" good it's to avoid an obvious annoying amount of vibration and noise. I like to keep my rpms as low as possible unless I'm purposely getting into it, but those 45 mph noises and vibrations are annoying when one is listening to music or conversing with a passenger and easily avoided by shifting to 6th 5mph or a couple of hundred rpms later. I agree with your data based statement that the engine is rated and designed to perform from 1k rpm to 6+k, but there's also plenty of things that manufacturers make that are designed to perform to a certain standard that still have optimal operation practices in the real world for longevity.

It's shockwaves going through the bottom end of the motor and is very bad for pistons, rods and engine bearings. It's a result of insufficient piston speed after ignition, when the air/fuel charge is detonated by the spark plug it wants to expand, and if it can't push the piston out of the way fast enough you get that sound and vibration as a result. Some motors are more effected by lugging than others, i.e. air-cooled VW motors hated it and American V8s tend to be more difficult to damage by lugging, but it's possible and the owner's manual warns against it specifically. |

To me the whole 1-4 skip shift thing is the definition of lugging, too high a gear for the vehicle speed.
The few times I let it happen I wasn't happy with the results, I would intentionally shift earlier or later into second just to avoid the forced 1-4 shift. If I got caught by the skip shift nanny I would just go to neutral and then go for second. PITA Then I just got the eliminator.
