I have a 2015 Tahoe PPV and was wondering if anyone had any information or literature on the competition mode on this model. I have driven it in both modes and have not noticed any significant differences. I am also curious about how active fuel management works on these if possible!

Do a little research:

 

"

The stability system is capable of recognizing high performance driving with a Track Detect Mode.
When continuous high performance driving occurs in 2WD or Auto 4WD Mode, the stability system will automatically enter
Competition Mode. When engaged, the message "Competition Mode" will appear in the DIC and the Traction Control OFF and
StabiliTrak OFF lights will illuminate. (see illustration section for StabiliTrak button location)
Competition mode can be disengaged by any of these four methods:
-Discontinue high performance driving for approximately 2 minutes
-Place transmission shift lever into Park for a brief period of time
-Press and hold button to completely disable Traction Control and press again to re-enable all stability systems
-
Turn engine off

Right, I understand that, but it doesn’t really explain what happens when you put the vehicle in competition mode. For example, does it adjust throttle response or just suspension and steering?

I would "assume" that Traction Control and StabilTrac will be off.

The "barn" still won't be able to go 200 mph.

Yeah, I was just trying to figure out if that was all it did. When driving, I didn’t notice any other changes, but I was just wondering.

Active fuel management is when the engine isn't under much load it will switch from 8 cylinder power down to 4 cylinder by shutting off fuel injectors to those cylinders

Oh, that is what I had thought! I can sometimes feel it switching between the two, especially on the highway. Thank you!

I know its 3 years late but if you drive the truck hard in competitive mode you will notice a significant difference in the behavior of the truck

The shifting is sharper, the steering stiffens up and the engine gets more responsive and will not drop into cylinder deactivation mode.

The truck will also run to its aerodynamic tops speed of about 162mph.

 

If you just switch modes and drive  normally won't notice the difference. Take the truck around a slalom course in the 2 different modes and you will notice

lol, there is no way a PPV is getting up to 160 mph (heck, the charger & taurus SHO interceptors cant even go that fast)

the driveshaft will give out well before that is reached.  tires would have issues at that speed too

 

129-135 is more reasonable, thats still pushing it.

i havent seen any upfitters upgrading the driveshaft

its pretty cool that it can enter competition mode automatically given certain driving conditions.

      6 Speed vs 8 Speed

      And to top it off finally.......................these small GM LS engines are designed to SPIN!!!!!  Why choke them down to just off idle for cruising.  Why/how the "bean counters" have influenced the "engineering department" at GM is beyond me.   They took a solid platform of an engine and turned into a joke in OEM form!!!

      Atlas,   Then following your logic we can't believe any story that the MSM produces? I mean it's documented they heavily donate to Democrat candidates. Vote Democrat in high percentages. Many MSM talents are married to Democrat politicians, Gov. employees. That goes for on-air and off, personalities and reporters. So they would all be biased and nothing they produce is to be believed in your mind?   Again the article simply was about ways AI can be used for pricing products. Nothing discounted current situations as a factor.    Again keep looking through your left/right lenses. I don't live my life that way.   And as a heads up this thread will be cleaned up again as much of this is off topic and is receiving

      So you're saying toss the baby out with the bathwater? @txab posted article was her take on how AI can be used to manipulate pricing as it already does and has been rebuked by the judiciasry in housing. How AI can be and is used to maximize refinery or even Amazon operations all of which are true but because she is who she is; that makes what she says about what is true, false? Is that something akin to Pre-justice aka prejudice?    Look, I'm first in line to approach all information with caution just because we live in a world where people like to lie about someone or something with such a straight face and in such volume that it makes digging to the truth wearisome. Meaning I understand the skepticisms but if I were to toss out everything a person is for a view they hold then my pool of people to draw wisdom from would be non-existent and I'd be forced to reinvent the wheel daily. Not practical.    "Be innocent as a dove but as cautious as a serpent."    Test each word. Every good lie is part truth or no one would believe it. Find the truth in it and reject what isn't.    On this one, AI is being used to do what has been done by hand for hundreds of years already but at such speed, the point of a computer, that it is more easily monetized. This one wasn't that hard a lift.    I wrote a few formulas in a Lotus 123 program decades ago, a series of linked Macros actually, that allowed a daily inventory to be turned into a running P&L and production plan. Something that took three departments a week to assemble now took the time it takes to input the 'daily changes' in inventory. Later that was ungraded to the more powerful Excel program an and integrated with bar code scanning, inventory to supply was done once per shift. It had a huge impact on production scheduling, Seamless interruption flexibility, inventory error reduction, raw materials cost effective utilization and scrap reduction. Huge improvement in the bottom line. I spent months on that and AI could have done it in minutes. So yes, it not only can be used, they would be foolish to not try. The legality, ethics and morality are not the domain of AI. Humans need to keep a reign on it.
