I'm wondering what is best for a 7.3 in the 425-450 hp range. Is a stock nozzle better for torque or 30% over? I understand nozzle size goes up as rpms rise the deliver all the fuel at the desired pulse width. I'm intending on using a t4 sxe type turbo just want to get use out of the injector size and not just big injectors for the sake of having big injectors. This is a 95 obs truck. That does tow. Some one please school me on injectors. Swamp's is who I do my business with.
