If you have the supercharger don't mess with any injector upgrade, get a 7th injector. By far the easiest, most hassle free and best preforming setup besides meth injection.

I see you have meth injection already though, you could just install a ~14gph nozzle and run pure methanol as well.

Are the 550cc injectors from bostch sequential will they match your fuel map and timing.

You would have to run some kind of piggy back or standalone ECU to get those injectors working. The stock ECU would not play nice with them at all.

For piggy backs, I have never been a big fan of larger injectors. Instead I prefer to add extra injectors and/or meth injection. That way everything runs stock out of boost and you only mess with stuff under boost.
