I've used TORCO in my FRS since 2012, stock and boosted, when I got a bad batch of 94 that showed knock, in travel through areas with no 94, or at Mosport , Cayuga etc. when the pumps are closed. The small amount (of TORCO) required to bring it up to 94 makes it economical.
In those conditions of over 7 years use, no problems were caused. All it did was leave an orange colour to the plugs and cat, and the cat did not plug up.
I am assuming the new competitors to Torco are similar.

Thanks for sharing some good points. I also see real real value in going from 94 Octane to approximately 99-100 Octane.
Orange plugs will definitely happen with octane boosters. In regards to that bad batch of 94 Octane you experienced... its always good to have 91 Octane back up map!
