Active runners on nitrous tune

[MichaelGardinier]

Tuning a 392 for a 100 shot. Car is running boostane to keep things safe. Had 18 max in her and saw knock (8 degrees) so I dropped it down to 16 and still still between 5-7 degrees of knock. Customer has ensured me the nitrous is jetted correctly, is it possible the the runners may be contributing to this? Should we disable them? He has the runners and nitrous on a window switch.

Thoughts? Really cant see it being true knock with 100 oct fuel and 5ish degrees pulled over NA.

Did the boostane have enough time to mix in the tank to make it to the injectors
