Please let me know which ECM you drive this with.
You will be driving 4 peak'n hold injectors. 
Hmm.. Does anyone know if the big P&H  TB injectors draw more
current than the little port-type peak'n hold units (as in turbo sunbird)?
Maybe a 7749 would be a good ECM to run the big Holley TB with..
It ran two peak'n holds per driver in the sunbird port injection app.
Thx
