Hi Richard; need help with jet sizing for Hellcat...HFS-3 with red circuit board...8 x 600cc injectors, 11psi max of boost, 50-50 mix

would 2 x .8mm suffice?

or should i go 2 x .9mm and dial it back?

and finally what restrictor should i use? .9mm?

thanks

What is the maximum duty cycle% of the fuel injector you are using?
