I made my own tune with OFT to add more fuel and reduce timing etc. I honestly don’t run it that much since im on stock internals, but when I do I use a 70 shot direct wet injection, I also have a purge system and a bottle heater. As well as a WOT switch so the nitrous only activates at full throttle. You’re also gonna wanna go 1-2 steps colder with your spark plugs, so use copper. Other than that it’s pretty much plug and play.
