If you go to the chips and emissions forums and do some searches you should find discussion on what changes are in most emissions chips. Mostly fan temps back to stock, idle speeds raised, and some other little stuff. Even with a 160 thermostat unless it's 20 degrees outside if you raise the fan on/off temps in the chip the engine will warm up to the fan settings. Just taking the stock emissions chip (bbjk) and changing the injector constant to match yours, and fixing the checksum, is all you most likely will need to do. If you are not using one of the chip editing programs like winbin or tunerpro, but a hex editor, set the first two bytes to zero and then calculate the checksum of the entire image. Then store that checksum in the first two bytes and burn the chip. If you got it right the check engine light will blink once then stay on, if it's wrong it will blink very fast, constantly.
With 50 lb/hr injectors I don't think you should worry about turning down the fuel pressure below 43 psi, they should spray well enough not to hurt anything. If you do turn it down, tweak the injector constant so your idle blm is about 130-135 at the lower fuel pressure since the next few blm cells where the engine will be at light throttle will usually be lower than the idle blm.
