Re: Question about RC brand injectors
Most injectors are rated at 43.5psi. You can run them at whatever base pressure you want though, it just changes their effective size. Too low of base and you will get poor atomization at idle/cruise. Too high and you overtax your fuel pump. If you were running the 750s at 36psi and then put the 1000s in at 36psi, then it is the same change as if they were both at 43psi as far as changing the fuel map. The 1000s might need different latency work, but that will mostly effect idle/part throttle and have very little effect on boosted fueling.
If you are using boost compensation in the AEM, then you should pretty much have the same fuel values at 10psi as you do at 30psi, so from 190 to 255 would be some decent headroom. You can change your Microbit/sec though to give you more headroom if you need it. Pretty much the Microbit/sec tells how much fuel injector on time that 1 raw unit in the fuel table is worth. So if you doubled the microbit/sec to make each fuel unit injector twice as much, then it would cut the values in your fuel table in half. It's not quite as easy as just changing that value, but it isn't hard to do.
