Supercharged 964...should I upgrade stock 19lb injectors?

I have a supercharged 964 and recently the piggyback ecu gave up, so I'm sourcing a replacement now. In the meantime, I thought I'd send the injectors off to be serviced/rebuilt. I can't believe 6 19lb injectors are ideal when you're putting down close to 320hp to the wheels.

Any thoughts?
I've not heard from anyone who actually owns a supercharged 964 (or even 993) and whether they have upgraded the stock injectors. I'll be able to fully map the new injectors, so no worries there. Most FI calculators are suggesting 44-60lb injectors for approx 350hp. Seems a bit much. I was thinking along the lines of 36-44lbs.
It's 90% street/daily driver...

Thanks in advance...

I use Accell 55lb injectors for 350 at the wheels.

Adaptronic is a capable ECU with great support from the designer/manufacturer/seller (all the same guys)

Thanks... Are you using an aftermarket ecu (motec/adaptronic/etc...) as well?
Care to share which injectors? Make/model....
