Your canned tune will not know to add additional fuel when spraying with your dry system or pull timing. If you had a wet system, your fuel jet would add the additional fuel. Nitrous accelerates the combustion process, you do not want any detonation. Approx 2 degrees per 50 shot needs pulled. I would not spray 100 shot on a canned tune or even a 50 shot. But you might be able to get away with a 50 shot. The higher octane gas will help, but I wouldn't risk it with out pulling timing. You can run your canned tune when not spraying, then take the time to load your nitrous tune when you want to spray. Or go with a wet system and a timing retarder and maybe your canned tune. Or the tuner can do the resistor trick in a custom tune when you want to spray. But a 100 or 150 non progressive shot on a street tire is probably going to be a handful. If you do a 150 shot, make sure your not starving for fuel. Need to play it as safe as possible, even if you do, sh!t still happens. Hope the fiancee has a fast recovery.
