They are deleting the chips on certain vehicles.

GM trucks losing another fuel economy feature due to chip shortage LINK General Motors will begin building some full-size trucks without a key fuel-saving feature next week due to the ongoing semiconductor chip shortage affecting the industry. The start/stop function shuts off the engine when the vehicle is not in motion and automatically restarts it when the driver takes their foot off of the Brake. It is common on many internal combustion engine-powered vehicles today. A GM spokesman told The Detroit Free Press that the change would result in a 1 to 2 mpg drop in the combined fuel economy rating for the trucks and that the price would be reduced by $50. The change affects certain trim levels of the following 5.3-liter and 6.2-liter V8-powered models with 10-speed automatic transmissions, including Base, High Country, Denali and AT4: Chevrolet Tahoe and Suburban GMC Yukon and Yukon XL Cadillac Escalade and Escalade ESV Chevrolet Silverado 1500 GMC Sierra 1500 In March, the shortage led GM to remove a cylinder deactivation feature from the 5.3-liter V8 that is also aimed at improving fuel economy by cutting fuel to some cylinders under light loads and said it wouldn't return until the 2022 model year trucks enter production later this year.

You have no idea what you are talking about.

No one will miss this but GM will likely have to pay some penalties for missing fuel economy targets.

No worries, they will pass them on to consumers.

You don't know jack shite. A computer control can't make an engine exceed it's mechanical capacity. Only an idiot would think that it can. You have to improve the engines mechanical capabilities first, by using stronger, lighter piston rods, lighter, easier operating valve train, roller tappets instead of lifters on push rod type engines and overhead cams on smaller engines. ported and polished fuel flow areas in the heads.
The computer programs are only governors, some programs govern less. The same engines without computer programs, and properly aspirated and tuned will give all of the power that the engine is mechanically capable of.

My god you are a moron.
Know how I know?
"ported and polished fuel flow areas in the heads."
Go read some more Hot Rod magazines.
"The computer is a governor!"
Where do people come up with this shite...

Tell you what Ace. Go pick yourself up a nice cheap 2004 Silverado and stick a carb on it then let us know how your drivability and mileage are. We won't even get into the emissions issue.
Edelbrock has several intakes to chose from. Holley can set you up with the carb.
You'll still need a computer since it doesn't have a distributor, but you'll figure it out I'm sure.

So you are a Hot Rod Magazine guy? I use to read those when I was a kid, and just starting to actually learn about engines.
According to your moronic logic, you could just slap a computer and some electronics on a model T and outperform a corvette. You can't give an engine higher mechanical capabilities with a computer program. It's maximum output capability is determined by the mechanical design, parts used. The computer can limit and adjust the parameters of the fuel/air mixture, spark advance/heat, but it can not increase beyond the engines maximum mechanical capabilities.

You would have to have A LOT MORE wires and relays. It would weigh a lot more, use as lot more electricity to power everything and thus use more gasoline and all of the electrical components would be a lot less reliable.

It can only increase performance within the engine's designed limits, it can't increase beyond the engine's natural capabilities.

The computers in the cars are why a 4 cylinder has way more power than a 350 from 1979 while getting more than double the mileage and 10% of the emissions
Uhhh. No. That is actually not the reason. Thats like saying the only reason Windows 10 is better than windows 98 is because of new processors.

So you don't know that fuel injection was invented way before a computer, and those fuel injected vehicles have distributors, except for the ones that are diesel.

Here’s a crazy idea! How about making it affordable to have all car companies manufacturer 100% of their products in the US?
It’s absolutely insane to be cheaper for US car companies…and all major to low level US businesses, manufacturer over seas and ship to the US.

You are right, and wrong, every engine has mechanical limits that cannot be exceeded, but internal combustion engines are not very efficient, computer controlled fuel injection, ignition timing, variable cam timing improve efficiency, enabling the engine to produce more power from every gallon of fuel used,and do it at any RPM, engine load and altitude.

Let me spell it out for you simpleton.
An engine runs on a mixture of fuel and air. Controlling this mixture is necessary for the engine to run correctly. A carburetor cannot control the mix as well as fuel injection and certainly cannot atomize the fuel as well. Both are necessary for power production and emissions. A good example of this is the high compression todays engines are able to utilize due to EFI. Gains both power and a cleaner burn and was not possible with carbs without high octane gas.
If one is only worried about maximum power without concern for drivability one can often come close to the same max power with a carb assuming no octane limitation.(That's not reality) However, driving that car anywhere other than a racetrack is difficult if not impossible as you are not using the engine at it's power peak. You seem to want to completely ignore this fact.
1200 rpm idles and powerbands that start at 5000 rpm are not what one wants in a daily driver.

Yes, that is exactly what I said. What a clown you are.
btw-I'm not a kid and actually know how to change jets, power valves and metering blocks on a Holley. Can also tune a Quadrajet pretty well. Have had 500HP, dyno tested, carbureted cars and every one of them would have been better with EFI.
I doubt you can say the same.
There's a reason Holley is selling the hell out of Sniper and other EFI systems versus carbs.
