Something’s not right with the formula.

Measured injector output in 1-minute = 150ml.
150ml/min x6 inj = 900ml/min x 60 min = 54,000 ml/hr flow rate.
54,000 ml/hr = 14.27 gal/hr
14.27 gal/hr x 6.15 lbs/gal gasoline @68F = 87.76 lbs/hr burn rate
Using the calculator at Connected Solutions - Fuel Injection Calculator and the values:
87.76 lbs/hr, 6-injectors, 0.55 BSCF yields 766HP with injectors at 80% duty cycle.
