The warranty has expired on my truck, and it is due for an intake and EGR cleaning per the maintenance schedule. Considering pros and cons of full deletes - Anybody have experience with it?
Cost wise, it’s a few hundred $$$ to get the intake and EGR cleaned, which will most likely end up just clogging up again. Cost to delete is about $2k in parts if I do it, more if I pay a shop to do it. Being deleted will reduce running costs due to improved fuel economy.
I’m in a state that doesn’t require diesel emissions testing. Goal would be a stock power tune to avoid smoking too much or breaking anything.
Besides the cost, and the risk of getting swarmed by hordes of babes that are attracted to my truck, is there anything else to consider?

Get a good tune, one that doesn’t smoke. I use diesel trucks for work, and the emissions systems are possibly the worst thing to happen to diesel trucks. They are more finicky than a methhead in church.

I’ve had a EGR on my diesel truck for 17 years and it has never been cleaned. Perhaps you should sell it and buy a European diesel truck. Or don’t use the truck for anything other than long road trips...

Thats the biggest killer a relative will use his for 20 5 mil trips a day, and has has issues since it never gets fully up to temp.

I’ve read on the Cummins forums that, besides fuel economy, performance is noticeably improved as well. You might not end up needing a tune at all.

what is it every 20k miles?
at that rate it will take 120k miles to make up the difference.
Doesn’t removing the EGR result in a leaner hotter engine at idle and worse fuel economy under load? I was under the impression you get a HP boost and mpg penalty.
I’m always hesitant about messing with engine settings if its a vehicle I intend to keep/daily rely on.

67.5k miles, Ram truck w/ 6.7.
Removing EGR keeps soot from exhaust from going back into engine, thus keeping intake clean. The exhaust has a DPF and SCR. How the DPF works is that it collects soot, then needs to “regenerate” to burn off the soot. It does this by injecting extra fuel into the cylinders on the exhaust stroke. Removing this will result in smoke (depending on tune), but less fuel usage due to no need to regenerate.

Need some form of tune when eliminating the EGR as well as the DPF and SCR in the exhaust. This is the most expensive part, the hard parts are relatively cheap.
You don’t need to add power though. Even at stock power levels, the MPGs should increase due to the truck not needing to burn fuel to regenerate the DPF, among other things. Percieved performance increases at stock power levels are from faster turbo spooling (due to less exhaust restrictions), or removing / reducing torque management programming.

The emissions equipment on a 17 year old engine and a modern one are night and day, regardless of country of origin. You are correct that diesel engines work best on long road trips. In my case it’s not economically feasible to have the truck for long trips and a second vehicle just so I don’t have to drive the truck for short trips.

Good info, thanks for that!

Perhaps. But mine is still far from an out of date thing even in the modern emissions context - all it lacks is common rail fuel delivery and a DPF - it’s still Euro 3 compliant.

Do it. Its the absolute best thing you can do to modern diesel trucks.
More power and better economy. Also no filling of DPF fluid. better for the motor too because only fresh air going in.
