Very true. There are engines which never need an IA fuel head.
#1 manage the fuel you have via adj. WUR, and check AFRs.
-------------
"Optimally you should tune all 3 points of the WUR so an RPM switch is not needed. I would never presume that boost hits at the same RPM in every gear in every situation."

Without the fuel head it may be theoretically possible.....but w/o the head you normally run out of fuel up high when the WUR is tuned for low to mids. RPM switch is required for a proper job - at that point, after everything el$e, scrimping on leaving out the low cost RPM switch is just foolish.

Adj WUR & RPM are a must, with the fuel head optional dependent upon the resultant AFRs.

Sounds trite, but a hi-po 930 for the everyman just does not cost all that much.
