Default injector size?

running the truck when it shifts into 3rd gear it falls off pretty bad. 4000# truck with 2000 LS1 with port matched heads, no other porting. stock ls1 intake, 228R cam, stock bottom end, LT headers WO/CATS, 3800 converter. could the injectors be maxing out in the higher load. Would an upgrade to some 36#ers support above mods + PRC Stage 2.5 LS6 heads + fast 90 intake

ok duty cycle on the injectors maxed to 80%. Timming never saw over 30*. I didnt have the wideband hooked up to HPTuners to log it but i think it was ok. The shift points didnt look very good though, they were at 6200 and when it went from 2nd to 3rd it dropped from 6200 back to around 5100 which was great just what i wanted. now what else should i be looking at in a log and do i need to change injector size for the above mentioned mods im planning for, and what should timming be at?
