personally I'm using snow performance stage 2 with dual number 3 nozzles (175ml/min nozzle each) fix at the bottom of the coolers just before the throttle body on each side and that's that best setup for me (bigger Nozzles tested and failed because of too much methanol injected) tried Nozzles number 4,5 & 6 (225ml/min nozzle 375ml/min nozzle 625ml/min nozzle) all tested with dragy (100-200 Km) times and the best tell now is to get 0.4sec faster time than (non-meth setup) still working on start injection psi and max injection psi which is a pain
