Default MPI fuel injector specs

Does anyone have the specs for the injectors? At idle and off idle. I have one that has 5.0-6.0 ms at idle and off idle it is 3.0-3.9. It seems to be backwards? It idles really rough and alot of fuel. The FACTS-New motor,distributor,computer(merc),alot of new sensors, etc. Also with the scan tool in service mode to set timing,The motor will actually rev up and kinda clear out. WEIRD!!!! PLEASE HELP !!!!!
