I've got a standard top mount but have a R33 Nismo spec fmic to put on when i get my uprated ram style manifold and down pipe. I also have a JAM actuator, HKS fuel cut defencer, and soon to buy a fuel pressure regulator. I want to take the boost to 1bar once the front mount and manifold/downpipe are on but, i have been reading that i dont need a fcd (especially an HKS one because aparently they make your engine run lean) at this stage of tuning! I am weary about running lean when i get bigger power and dont want to buy another fcd. Does anyone know if i will be safe by putting the HKS
