What kind of octane are you guys that are running high boost AND nitrous using?

I was thinking its purely C16 land, but I thought I'd get some points of reference from you guys

 

C16 and timing adjustment. I have found that the VP Import does not like the nitrous as much, especially in hotter atmospheres. It does have a slightly higher gravity spec. It is about 123 octane.

For reference as well, what kind of boost and how much nitrous along with approximate ign timing?

I was thinking something along the lines of 22-23psi + 50shot @ around 17-18* ign timing would be ball park? For reference I run 110 octane with 22-23psi and 22* ign timing at the moment.

Thanks
