Running 450cc Primaries in TII?

I have 2 720cc for secondaries. I have a RB ful exhaust. No Standalone, so my 720 wont be controlled. Just so I dont run to rich when around 4000 rpm, should I just use 450cc for primaries instead of 550cc?

the owners i bought the car from had n/a injectors with 720's on the secondaries.

They are idiots and im hella pissed cause i probably detonated my motor 1000's of times by now. ANd im on the works to put 550's back in the primaries.

so x3

definitely not


it might have been an idea if all 4 injectors were fired together but the fact that the primaries are used solely when beginning to boost until the secondaries come on and will be starving the engine isn't a good idea.
