it would extend the life of your truck by doing the deletes. That being said, if you race your truck or do not use it on the highway…. Technically these modifications are not road legal if you drive your truck on public highways in the US. More efficient as far as MPG and HP without the restrictions or regen cycles.Improves exhaust flow, turbo spool rate and lowers your exhaust gas temps, mainly because the restriction is no longer slowing the exhaust gases after the turbo.Drastically slows down the bad oil dilution problem that 6.4s have, which decreases wear and extends engine life.Some people remove the DPF and not the EGR by simply doing a DPF delete along with a tuner that prevents the engine from going in to the Active Regeneration cycle (Cleaning Exhaust Filter). You can read about that at ‘ Ford’s Diesel Particulate Filter (DPF) (Exhaust Filter)‘. You can delete the DPF and leave the EGR, but not the other way around. What About Deleting Ford’s Diesel Particulate Filter (DPF) (Exhaust Filter): Removes the risk of premature engine damage from EGR system failure.Extends the life of the EGR cooler because there is no more 1200 degree exhaust gasses passing through, which can cause the coolers to crack and fail.Better MPG by eliminating hot exhaust gasses from entering the intake.It will reduce engine power, and causes excessive wear and tear on the engine, due to the higher temperatures that EGR equipped engines run at, compared to diesel engines with no EGR.ĮGR has proven to destroy turbos, increase cylinder pressure causing head gasket failures, cause piston failure, as well as other problems. Soot build up in your diesel’s intake system is never a good thing. So while C02 in excess can be a bad thing, a little bit can actually be a good thing. Replacing blown out LH manifold gasket and half the parts are off. I know the 6.0s will play nice, not sure about a 6.4. This soot is full of carbon (C02), which plants use as food. Can you do an EGR delete without tuner 6.4 Aftermarket. If you feel a little soft (and you have the mods support) you can try the tracks +185 or +250, really open the truck. keep the push under 40 psi if you are still on stock head seals and bolts. These spent exhaust gasses are full of soot that would normally exit the exhaust pipe and fall to the ground. The 6.4L tends to work better as a daily driver to the +135 HP tune with EGR and DPF deletes installed. The downside is that it also results in a clogged up intake system. The way EGR does this is by allowing exhaust gas (which is lower in oxygen) into the intake of the engine to lower the combustion temperature. These gases contribute to the formation of smog and acid rain, as well as tropospheric ozone) being expelled out of the exhaust. What the engine manufacturer’s attempted to accomplish here was lowering the NOX emissions (NOX is a generic term for the nitrogen oxides that are most relevant for air pollution, namely nitric oxide and nitrogen dioxide. If you’re new to diesels, you’ve probably heard this term, but don’t know what it means.ĮGR stands for Exhaust Gas Recirculation.
