Upgrade to 36lb injectors

At OEM pressure and with your additional cubes, I can see you pushing
those 30's to the limit

I like to tune as Ford does with OEM pressure

If you don't wanna up the pressure you only have the other option which is to go with larger inj's

Seems like to me peeps have said 36's are hard to find these days

I'm in pretty much the same boat. I plan to throw a turbo on it w/83lb injectors so I will be bumping my pressure until that happens.

I say if your not making more changes get the 36ers. If more power is on order bump the pressure until those mods are done and get 42's.

Just know if you already have your CL portion of the tune all setup
and stable ... upping the pressure is gonna hose up that part of
the tune

I'm not a fan of bumping pressure to get more fuel. The injectors have a designed fuel delivery rate and are good to deliver that fuel to the 80% duty cycle at the specified pressure. When you exceed the design specs fuel delivery is no longer consistent which can result in AFR's that may not be reliable and/or consistent as well. Since larger injectors can always be tuned to actual needs it just seems foolhardy to gamble with undersized injectors by jacking up the pressure.
