350TPI Fuel Injectors

[Bruce Plecan]

Supercharged with a MAF you'll peg it at less the 2K RPM is my quess.
Really should figure on running a 749 ecm, IMO.
Unless you figure out how to run a late 3.5" MAF.

Has anyone looked at or studied the 6E or other code to see what happens
when the MAF overloads the input?.  On the gn list there has been comment
that when it overflows the ecm starts over figuring the grms/sec..  So might
read 255 and then in the next frame 14, next 30 etc.
