I run a V6, but wired the same as the drawing above. 3 sets of paired injectors. the cylinders paired one crank rev (360 deg sh) apart. I have my engine set with a VE of about 50% at idle, And I get up to 115% at 4000rpm and 0.3 bar boost. Revs to 7000RPM and A/F of about 12.5:1 across the board.
Two squirts per cycle. This gives each cylinder a fresh squirt of fuel just before/during the inlet valve opening, and a one that has been waiting.
Dead time is for the opening/closing time of the injector once. Speeduino takes care of 2,3,4..... squirts per engine cycle (720deg crank)
It is well documented in this forum of switching between 2 and 4 squirts per engine cycle to check on your dead time settings. As if it is correct there should be no change in Air Fuel ratio.
As theonewithin said, make sure you are not maxing out your injectors. And your fuel pump is not running out of high end flow.
