In order to do a proper EGR delete You have to do following:

MX13 EGR delete ECM tuning.

block off EGR gas flow.

unplug EGR valve connector.

unplug EGR sensor connectors.

ECM tuning:

Our ECM tuning will allow you to block off EGR valve and unplug all EGR sensors.

Keep in mind that along with EGR delete, we must delete all the filters on exhaust (DPF DOC SCR), and DEF.

All our MX13 EGR delete tunes come with a fleet safe power upgrade.

This upgrade will provide You the best fuel economy.

List of all our delete tunes for Paccar MX13 engines.

EGR delete - block off:

The basic principle for blocking off EGR is the same on all engines.

EGR has to be blocked with steel plates on both cold andamp; hot side.

1st block off plate goes on position where EGR manifold meets exhaust manifold (hot side).

2nd block off plate goes on position where EGR manifold meets intake manifold (cold side).

The reason we recommend blocking off EGR on both sides, is because that way engine will run the best.

Once You block off intake(cold) side, your intake manifold air volume andamp; geometry will not be messed by EGR tubing.

There will be no chance of sucking air from EGR manifold, and that way causing an air leak.

Same thing is for exhaust(hot) side, your exhaust manifold geometry will be again according to factory spec.

On photo below, red arrow points out to EGR's hot side plate position.

The engine on the photo is MX13 EPA13, but MX13 EPA10 andamp; EPA 17 engines are very similar.

EGR's cold side(intake) plate position is on photo below.

The photo is from MX13 EPA10, but all other MX13 engines are similar.

Unplug EGR valve's electrical connector (location varies but should be easy to find).

Now we need to unplug EGR sensors.

There are two types of sensors we need to unplug:

EGR differential pressure

EGR temperature sensor

Below are the photos of EGR sensor's locations on Paccar MX13.
