Another EGR question

[Nismo1182]

So while my engine is out of the car, i have access to the egr system. Now if i take out the actuator off the intake manifold, it will leave 2 small rubber hoses. Those 2 hoses run to some sort of small solenoid system bolted to the back of the head. Also the FPR runs to them too as well as the 2nd butterflies. Now, I want to remove the egr, the butterflies and reroute the FRP hose to another part of the manifold. I want to remove that small solenoid system.

Will it throw a engine code? Or will the engine run like crap?

Ive heard removing the egr will cause the engine to ping, does it also do this with 93 octane?

it will throw a code...and the engine will ping on ANYTHING LESS THAN 93 OCTANE.
