lower flow rate injectors

Hi,
Per megasquirt's calculator, I only need injectors that flow around 15lb/hr if I make some exhaust mods that will open up a few horses on my '82 380sl Mercedes. The 3.8l V8 just doesn't need that much fuel. My question is, I've only seen Bosch injectors (Ford) at around 19lb/hr. Who makes a quality injector that flows down in the 12-15lb/hr range? Given the disc/pintle threads I've followed, I think I'd like to have disc-style injectors. If I can't find any, what says the group about the third generation ford 19lb injectors... They're supposed to atomize fuel better than the four pinhole model?? I'm still in the planning phases for my project, but am down to selecting injectors. Thanks all!!!

You shouldn't have any problems with the 19 lbs. injectors. The only difference from smaller ones is that after you finish tuning the maximum duty cycle will be lower, for example 70% for the bigger injectors instead of 90% for the smaller ones.
Running very oversized injectors can effect the idle quality but from my experiance you'll have to use much bigger unjector to get that problem.
