N55 spark plug gapping for future tune

The time has come to change my spark plugs and I am looking to add bootmod3 stage 1 on my f30 335i xdrive in the near future, maybe 5k miles. I ordered the NGK SILZKBR8D8S (97506) and bootmod3 recommends to gap them to around .023". Will it be fine if I gap them to that spec with no tune or will it cause a rough idle? Let me know your thoughts and experience. Thanks
