The water temp sensor and charge air sensor read differently on 3i and frst it will run with either but if you want it right then swap them for frst ones then you know you can increase boost etc without any issues with sensors.As for the surpresor it will run fine without it but it WILL do damage in the long run so if you are going the ofab route then get the surpresor,If you dont need it then it wouldnt be there in the first place,its there for a reason so get one.
