both injectors are ALWAYS firing... what opens at 3750 is the secondary intake ports... it is a butterfly system...
and go with a wet... just cause your motor is useing more fuel doesnt mean it is just being sprayed for fun... it means that it needs it... so in adding nitrous you will need MORE gas... so, WET...

Actually both sets of injectors are NOT always firing. At least not on FCs. The primaries are ONLY on until around 3800. Then the secondaries kick in and the primaries cut down on the fuel they add. And the primaries are on a different rail than the secondaries.
