BBR tuning at home kit, 2.0 CX5 2013, run on 99 octane?

[zebedee]

Am thinking about getting the Bbr kit which takes hp up by about 11. Am wondering if before getting it, should I put a few tanks of 99 through and optimise it for that or would it not make any difference?

11hp - you'd be better off having a poo before you drive it

I can't recall the last car I've seen bouncing off the limiter on the road so until you are doing that in every gear, save your money

They're 11 tuner horses too, so about 5.5 OEM horses.
