Plenum Pull / EGR Delete

[ZX-Smoov]

I've search this forum for an explanation for the value of doing an EGR and water lines delete. I pulled my plenum... The number one answer is now self-evident!
In not interested in reconnecting that crap when I reassemble.
Other than that, any technical or performance value to doing the deletes? I've concluded that I'm yanking that s*** out anyway, but wondered what wisdom is out there on the subject.

The basics are covered in the "Everything you need to know" post stickied in general. In short, the coolant lines are there for extreme cold weather climates to pre-heat the manifold and the EGR once removed no longer dumps exhausted gasses into combustion, this can theoretically result in higher combustion chamber temps but like most things with proper tuning can be alleviated.

The EGR on lowers combustion temperature, with it disabled the engine may ping because running the EGR slows down the burn. The OEM timing often advances slightly to make up for the slower burn, it may be slightly too far advanced, retarding until the ping just stops is the cure. If the coolant hoses get blocked off the extra cool under the intake may offset the EGR gone to not ping.
