Has the idle port on the throttle body been modified to only allow flow to the IAC passage. These throttle bodies were designed for TPI cars as well. This is most likely the reason for the split blms. On the running rich, have the voltage offset tables and low pulsewidth tables been modified for the svo's? I have a 42lb injector equipped car that Iv'e been working with that would hard start and idle poorly until both of those table were properly adjusted. Scott Knight posted a thread on here about dialing in a set of 83 lb/hr Siemens injectors that had some conversion math and use of a cool program , Scilab, to generate a corrected table based on data from the Ford worksheets.

You might need to reduce the startup VE and lower the closed throttle timing at the 0 and 400 rpm points
