Nitrous is good but it does take some setup and tuning. Your running compression jumps way up with nitrous. The key is balancing statistical compression with your head and the running compression with the pipe design port timing and nitrous all together. To make it reliable piston to cylinder clearance, ring end gap, head design, and timing are key changes. The biggest downer with nitrous is you have to run race gas if you are gonna push the button and when your not sucking nitrous race fuel isn't needed. So you either have a detuned zilla off nitrous or a beast on the nitrous.
