Injector questions How bad will the car run with 42lb injectors compared to the stock 26
if the injector duty cycle is above 80 % will a fuel pump bring the number down due to increase in pressure
if the injector duty cycle is above 80 % will a fuel pump bring the number down due to increase in pressure
WHOA there!!

Without some background info, that ? is totally confusing.
Duty cycle of which inj?
Why 42's to begin with?
What's the op pressure to begin with?
What is the FWHP target?
How are you going to achieve your target? Blower, NOS, ??

You need to have the tune done again or the car will run like **** if it runs at all. You shouldnt be to far off if you just change injector flow rate it would take like 2 min to flash in the new ifr table. If you have adjustable fuel pressur on the pump then you will be able to compinsate for the new injectors but you would still probably need it tuned for the extra fuel that would be coming in from more fuel pressure at low rpms. You need to upgrade the fuel system to make big power just go a head and buy a new pump and injectors and you will be set for a while on you fuel system.
