Herein lies the problem....
I
HATE the word "UPGRADE" because more often than not, the "upgrade" isn't much more than a headache or a total waste. I do not use that term for ANYTHING regarding aftermarket parts on a truck (heck, I don't use that word for anything, period because it bothers me so much). It's become such an overused term that means very little....
On a side note, my computer just reminded me of a Java Update that's now available; time to close that bubble and ignore it.
...anyway, it means very little because NOTHING that one can do to a truck is actually going to make it any better in every regard than the stock hardware. If you want more power, by all means install higher-capacity injectors and add larger nozzle orifices if you want to. However, to believe that the truck will run, drive, maintain EGT, or even get better fuel economy than stock is only proof that you're fooling yourself. The internet and it's wonderful forum communities have got every Tom, ****, and Harry thinking that "upgrading" is the only way to make the truck better or more useful. It couldn't be farther from the truth because in this instance, installing "upgraded" injectors is akin to willfully lighting one thousand dollars on fire and complaining about it the whole time.

He could buy the injectors if he wants to and not even change his tuning (stock or aftermarket). However, it will run and drive exactly as it does right now. AA code injectors are identical to AC (160/0%) injectors save for the increase in fuel capacity. If you're familiar with the HEUI injection system (or even just the "fuel side" of the injector), you know that there is a fixed capacity of fuel available per injection event. The AA code injectors' capacity is just over half of what the AC codes are capable of holding at one time depending on who you listen to (good ol' internet and the "facts" that are out there). If installing 160/0% (AC code) injectors into a 1995-1997 F-series without tuning, the injectors will only be commanded "on" long enough to inject the same amount of fuel as the stock AA injectors. If exhaust gas temperature is marginal now while towing, then it will be even hotter when more fuel is injected to make more power. Keep in mind though that the specific injector change you're considering won't inherently make the EGT higher.....but the tuning required to make the injectors a worthwhile investment will.
In closing, if your truck runs fine now (no injector problems), I wouldn't waste my money given the usage of your truck.
