EGR Delete really necessary?

[6.0DJ]

So if I get a filter for the radiator, install a better exhaust, SCT 3 system, head studs, blue spring upgrade kit (for fuel pressure), and a new oil cooler.

Do I really need to delete the EGR?

What are the benefits of deleting?

HP gain?

Fuel efficiency?

Thanks for your input on this.

No, you do not need to delete the EGR. You can just replace it witha higher quality one, like bulletproof diesel's EGR cooler. The main reason for deleting it is to prevent it from rupturing if your oil cooler gets clogged. The other benefits would be that you keep te hot exhaust gases out of the intake which may help with the efficiency of eht engine, but not much if at all.

I had new heads, head gaskets, egr cooler, and oil cooler done at 111k. I have elc with a filter and my sct tuner turns off the egr. I now have 153k with a 4 degree delta and no problems. I think if ya just turn it off then hot gasses will not flow through it. If it is not leaking and you Are not putting heat through it then it should never leak.

no you dont NEED to do it. you also dont NEED to do the head studs. you do not NEED to do anything on the list but maybe the blue spring update. but if you are going to do that stuff, for another 300 in parts its a no brainer as you already have it all torn apart. deleting the egr cooler just eliminates a weak link in the chain.

No it's not needed. It's only suggested to prevent possible engine damage.

custom tunes commanding the valve to not open is different than blocking exhaust gas from entering the cooler or removing the cooler. Exhaust gas is still traveling through the cooler if you haven't blocked it or removed the cooler. You can't 'turn off' the exhaust gas from traveling through the cooler, you can only 'turn off' the valve from opening.

if you turn off the valve from opening, or unplugging it in the closed position or installing a spool, exhaust gas will enter the egr cooler, but will go no further. it will not circulate. its got nowhere to go. it will be stagnent air that is only heated by the up tube and engine heat.

That is not correct... On WOT runs the valve is forced open from too much pressure building in the cooler and the gases ARE let through the valve.

The ONLY way to be sure that NO exhuast gases enter is by plugging the end of the EGR cooler by the exhuast up-pipe with a steel plate (blocking plate welded shut) OR putting an EGR delete on the truck.

I wouldn't recommend unplugging the EGR valve electrically, this can cause issues with certain strategies and year trucks.

^^This. Unplugging it is no longer recommended by most.
