06 mustang 95mm cai + nitrous

[1fastfalcon]

Running the 95mm 91 oct intake tune and I pulled 5 degrees of timing which put my wot timing to 22-23 degrees. I want to run a 100 shot on a zex kit. I don't see a 87 oct 95mm tune that would drop timing more. Is 22 degrees to much for a 100 shot? Also I have an off road x pipe can I get a tune to turn off the rear o2?
