I’m looking to enhance the performance of my 2018 Chevy Silverado by disabling the AFM (Active Fuel Management) and DOD (Displacement On Demand) systems. I’ve read that these systems can affect the engine’s responsiveness and overall performance, especially when towing or during spirited driving.

A few questions I have:

  • What are the most effective methods to delete or disable these systems?
  • Are there any recommended kits or software that I should look into for this process?
  • I’d love to hear any personal experiences or tips from those who’ve gone through this. What challenges did you face?

Also, are there any potential downsides or things I should be aware of before proceeding?

Any guidance or shared experiences would be greatly appreciated!

Hey everyone, I’m looking into deleting the DOD system on my 2018 Silverado. Does anyone know about the legal implications or potential fines associated with this? Would love some advice!

It’s a good question, wendywise! Deleting the DOD might lead to issues with emissions regulations, and you could face fines or fails during inspections depending on your state laws.

I had a friend who deleted his DOD and got hit with a hefty fine after his first emissions test. It’s definitely something to consider before making changes.

It’s crucial to understand your local emissions regulations before deleting the DOD. Some states have strict compliance rules that could catch you off guard! #StayInformed

Wow, that’s a scary thought. What specific fines are we talking about here?

7

Fines can vary widely. I’ve heard anywhere from $500 to $2,500 depending on local laws and the severity of the infraction. This can add up fast!

8

Not to mention, if you’re caught, the fines are often just the beginning. You may need to reinstall the DOD or face having your vehicle deemed non-compliant.

That’s good to know, fwright. What about emissions testing? Is that different if you modify the engine?

Yes! If you modify the engine, many places will require you to re-certify your vehicle for emissions, which can be a hassle. Just something to consider before proceeding.

Honestly, it’s a tricky decision. Sometimes I wonder if it’s better to just deal with the AFM issues rather than risking fines. Do you all think it’s worth it?

That’s a tough one, jasonsuarez. If you’re often facing DOD-related problems, it might be tempting. But the risk of fines definitely weighs heavily on the decision!

Look on the bright side, at least it gives you an excuse to breathe life into your project car! Just make sure to keep your ducks in a row with emissions.

I’ve debated removing the DOD on my '18 Silverado too! From what I’ve read, it seems that doing so can improve throttle response and overall performance. Anyone noticed a significant power gain?

I did the delete about six months ago and it felt like a completely different truck! A noticeable boost in power for sure.

I’m curious about fuel efficiency post-delete. I’ve heard mixed reviews—some say it goes up, others notice a drop. What’s the general consensus?

17

After removing DOD, my fuel efficiency dropped about 1-2 MPG. However, the power gain was worth it for me! More fun driving is always a plus.

Definitely! But did you feel any adverse effects on engine vibrations or noise?

I noticed a bit more vibration but nothing drastic. Honestly, the extra power and better throttle response made up for it in my experience.

Sounds like a mixed bag so far! I’m excited yet nervous about the potential trade-offs. What would you say is the biggest pro after deleting?
