Another "Is Fuel Injection a Worthwhile Upgrade?" Question

there is no sequential in a TBI, not possible as they run into a common plenum. all TBI is batch fire. MPFI can be sequential...my Pro-Flow is 4 channel, 'semi sequential' as it groups 1-8, 4-3, 6-5, and 7-2 injectors with the same pulse . Sequential is mainly for start up and low speed emissions as sequential is still hitting a closed valve after about 3000 RPM as the duty cycle is not fast enough to trigger to an open valve after that. The max effort engine pull and F1 12K plus RPM stuff is way up the tunnel ram runner, even a fogger system at the plenum or even over it, just like the old Holley Pro-Jection systems and others that use the 2-4 injector pods over the blades and have an idle servo that kicks the throttle open a hair for idle.
