Delete Kit: Better Mileage or Just Better Performance?

[hosapik]

Hello everyone.

For anyone running a diesel delete kit, I’d like to hear about your experience after the initial installation period. Did you actually gain fuel economy, or did the improved performance simply make it easier to use more fuel?

I’m particularly interested in highway mileage, towing performance, throttle response, and how the truck behaves under load. Were there any reliability concerns that showed up later?

Also, did the truck require any additional maintenance compared with the stock configuration? I’ve read plenty of conflicting opinions online, so firsthand feedback would be helpful.

If you’ve had yours installed for a while, would you recommend doing it again?

I’m particularly interested in highway mileage, towing performance, throttle response, and how the truck behaves under load. Were there any reliability concerns that showed up later?

Also, did the truck require any additional maintenance compared with the stock configuration? I’ve been researching a 2021 6.7 Cummins delete kit and have read plenty of conflicting opinions online, so firsthand feedback would be helpful.

If you’ve had yours installed for a while, would you recommend doing it again?

thanks in advance for any help
