The highest injector duty cycle I have seen on my logs is 68% and that was at a 10.5 AFR at about 20 lb of boost. So it was Pig rich and still had plenty of fuel flow.
I didn't really see a need to upgrade it and it basically screws right in to the fuel rail. I don't plan on going much past 20 psi because I can only get 93 octane where I live.
Just want to add. As for being tuned. I'm using a timing table from someone on MR2OC with a similar setup with a few degrees pulled out, being that the alltrac is a heavier car so more load on the engine.
Megasquirt/tunerstudio has a nice autotune feature for the VE tables. Just make an afr table of what you want and when you want it and it will fix your tables for you. Might need to fine tune some of the lesser used parts of the map but its easy to blend it.
When in doubt I just run it a little bit rich.
