with the advent of more modern turbos and more competent injector tuners, is it reasonable to run injectors reliably at a lower rating?
I have seen many people running 200+ cc injectors on daily driven vehicles.
Can we now run big injectors as daily drivers? I'm asking because I don't know.
I've also seen people running 238cc injectors and claiming they have been detuned to reasonable levels with reasonable driving characteristics..
I am similar to @FinnishStroker in terms of vehicle modifications and usage pattern, especially the part about driving solo. However, I do not think mine is so much detuned bigger injectors as it is matching the turbo to the injectors. I have not changed anything with my tunes but my smoke and EGT issues went away once I changed to a more efficient turbocharger setup. I will be changing a few things to allow higher boost levels to see if that improves matters somewhat with the extra air. Boost is currently limited to 35psi because of other constraints.
If you detune a larger injector, say a 238/80 for towing. Would the atomazation suffer, causing more egt issues or smoke?
Does it make more sence to run something like a 205/30 and use more of its potential then run something like a 238/80 and run it detuned a dcent amount of the time.
I assume this comes into play more when towing.
All this with the assumption that everyone understands the better matched the turbo is, the better any setup will perform.
Detuning doesn't affect directly to atomization.
Atomization is a result of injection pressure.
The relationship of nozzle size and ICP determinates IP.
Detuning is simply cutting fueling.

In other words, icp stays same, pw is what changes? That makes sence. Now 30 percent vs 80 for towing with a hybrid? Decisions are hard lol
Also all the same. Say 425rwhp 205/30 vs 238/80 the 30 nozzle should atomize a bit better and be cooler and more efficient towing?
I currently run spx wheel with kc turbine, so nothing fancy.
my last towing trip consisted of a run from Espanola N.M to Denver and back, 5k equipment trailer empty coming back 02 f250 crew cab on it didn't weigh in but safe to say easily 12k+/- 238/80 bitter root injectors .
Trip up empty php titan 65 Performance tune never egt issue at all, loaded 25hp heavy tow only time I had to drive by egt gauge was going up 9k' pass.
in 25hp tune my pw was max about 2ms, and 99% of the time truck ran cool with plenty of power on tap.
Running 315 75 16 with stock gears loaded, easily handled interstate speeds in 6th.
unloaded commuting the truck in 65 tune is WAY quicker than any stock injector hot tune, speed will get scary before temp does.
