Injector Tuning... since i dont wanna hijack the SVO thread anymore... does ANYBODY have racetronix 42# injectors in their car? can they send me their IFR table?? i have no clue what i need to change this stuff to and id rather not **** it up 
injector specs:
Delphi/Lucas 42# High Impedence Fuel Injectors
-Static Flow Rate: 42.29 lb/hr @ 43.5PSI
-Static Flow Rate: 48.83 lb/hr @ 58.0PSI
-Dynamic Flow Rate: 9.96 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 43.5PSI
-Coil Resistance: 15.9 Ohms / High Impedance / High-Z (No ECM driver modifications required)
this is what im coming up with??
MAP (kPa) 0 5 10 15 202530354045505560657075 80
Injector Flow (g/sec) 6.15258 6.190924745 6.229033451 6.266910425 6.304559843 6.341985758 6.379192104 6.4161827 6.452961256 6.489531379 6.525896571 6.56206024 6.5980257 6.633796174 6.6693748 6.704764631 6.739968642
