Jesus what has happened to my thread lol

anyway, the exhaust manifold and intake manifold have been on the car for a couple years and ive read that people do seem to like the intake manifold but hate the exhaust manifold. I do plan on going with a greddy intake manifold and a Tomei Expreme exhaust manifold and dump pipe, greddy FMIC, go with a gt28, either go with 480cc or 550 cc injectors, 255lph fuel pump, full 3 in exhaust from turbo back, z32 maf but im trying to figure out what system i want to use, i really dont want to spend money on the AEM EMS cause thats a bit expensive and i really dont need that, i was looking at the e-manage by greddy but idk, anyone got any thoughts on what i should run and i was thinking just having tuned at 12 psi and call it a day
