I'm currently on the cm5 myself and looking forward to switching to a cm7. Maybe this can help us inject a little later with better cooling? Ricked_em let us know if you see a difference with iat. I actually dropped a bottle of HEET into my jug of snow boost juice. Not sure if it made a difference or not.
I'm honestly hoping with the slightly bigger nozzle and going to a 70/30 mix I'll gain some octane boost. If I can keep ambient or slightly below and get a little octane boost I'll be happy. Honestly everyone needs to email CTS and tell them to make one of these for us - https://www.moddedeuros.com/products/cts-turbo-fsi-throttle-body-spacer-06-08-gti-jetta -so I can run a cm3 in the throttle pipe and a cm7 in the spacer.
