Default 2000 281SC stumble

Does anybody know what fuel injector LBS. should be installed?, I think I have 30# installed from the previous owner, and what heat range should the spark plugs be, the reason for my questioning is when I step on it after its warm, it stumbles unless I floor it, then the Supercharger kicks in and overides the problem, which would be fine, if it weren't the fact I'm using up excess gas, it has like a miss when its heated up, if I hold at a a certain RPM, it miss's and if I come to a light, it wants to die and I have to actually keep applying the gas when it drops down to keep it from dieing. Any help would be appreciated, I hook up a DTC code reader and it doesn't show a code to analyze, I'm running out of idea's !! Thanks !
