Default Injector advise

I have an 04 GT with Stage 1 and an S2 Wastegate Accuator dialed in to 13-15 lb. of boost. At WOT I'm seeing Injector Duty cycles in the 85-90 range, and I'm thinking I am overworking the injectors. I was told I need to go with injectors one step larger to bring them in line and get a little more out of the boost I am running. I have the Getrag trans and it all runs well. I do seem to run out of power in the higher rpm's though. Any ideas on what injector size I should look at? Are the stock 04 turbo motor injectors considered already as "S1's"? I would like to swap them out and not get into other changes like a pump upgrade.
