If you want to try it out, go for it...what's the worst that can happen? You ruin an injector and have to either get 1 new one, or spend the money on 4 new injectors which you seemingly want to get anyhow. Sounds like a win/win situation even if you mess up. I'd be down to helping you out if want to, we can also test the spray pattern and cc/min for each injector. I say go for it.
