AHU EGR Delete

[Afterhours]

I’ve been looking to delete the EGR cooler on my AHU and I was curious what some people have done. I have a PD130 intake with the mk2 gasser coolant hose for the back of head to heater core. Is there anything else I might need or something to watch out for while doing it?
Thanks!

Just make sure you have a block-off plate for the EGR port on the exhaust manifold, other than that it's pretty straightforward

You may need to get a silicone hose to convert to the factory charge piping depending on what adapter you have on the pd130 manifold

PD130 gearbox facing intake+ race pipe plus silicone angled coupler and clamps of the correct size…
Block off plate for the exhaust manifold
Coolant hose splice or a single hose for the little coolant hose to the coolant ball
mk2 2.0 gasser coolant hose for the head to heater core hose.
Tune to tune out the EGR

whether the egr delete helps or not can depend on many things.... without tune, i think it might be helpful to avance physical pump timing a bit, maybe 1/3 above the blue line. you'd just have to feel it out. the reason for doing physical pump adjustment is because that will force more advance in the lower rpm areas where egr is most active, and more timing will be likely be needed, but it won't affet the other areas because spec timing is already more than that

I was going to email you about getting a tune after I install everything. But that’s good to know thank you!
