Which is best, bigger injectors or fuel box for more fuel?
If I wanted more fuel which is the best route. Install bigger injectors or install a fuel box to get more fuel?
What would be the difference?

Both would provide more fuel.
A fueling box, depending on make, can add fuel, control timing and boost fool. Most are adjustable. Which I prefer. This allows for you to run less fuel or a less aggressive truck when you don't need the power on tap. Many of these boxes are described to have a "hit" with the fueling. Boxes that add timing can increase milage.
Injectors provide for more linear power. They are always "on". Mileagle increases can sometimes be had here as well. Obviously, the only adjustment is made by your right foot. Less responsive than a box, but much more progressive.
In the end, it depends on what you want to get out of the truck. Most go to a box first to get the built in boost fooling and adjustability. Injectors almost always follow. But, I recommend getting a clear idea of what you want the truck to do and build it accordingly. Nothing worse than adding a bunch of go fast parts and finding out it's not driveable for it's intended purpose.

There is something of a spectrum involved, in that you can bias your additional fuel delivery to either a box or some injectors. For example, the larger the injector, the lower you can run the box (and, the lower you may HAVE to run the box) in addition to having less fuel you can "turn off."
I personally love the linearity of larger injectors, and I'm running injectors that considered to be quite large for a stock turbo. They probably wouldn't work very well towing heavy-- but fine for lighter loads under 12K or so.
Electronics give you control and versatility-- and injectors alone can't do much without a good fueling module of some kind.
Another variable is that fueling boxes don't deliver the fuel in the same manner as injectors. Injectors just enlarge the factory fuel pulse (in terms of fuel CCs). But a module can actually change the duration of the pulse.
All else being equal, getting more fuel in a single pulse will have lower EGTs than extending the pulse.
I went with the largest injectors I felt I could drive on a daily basis forever, while still having something big enough to meet my HP goal of 500 if I can ever get there.
For me, the Mach 4s have been perfect all-around, and I really couldn't ask for more from an injector.
I'm still unsettled on what I want to do for electronics. Quadzilla's products to me appear to be the best available for the 24V, since most manufacturers have abandoned the VP trucks to focus on the newer, more popular HPCR trucks.

I want to keep the everyday truck drivability, while being able to tow a 11,000 lb fifth wheel. I don't want a hot rod, just a little more fuel or power.
The Puck has been GREAT!!! It really helped fuel mileage and power. In the future I'll also get a valve body.
Also, how do you stack boxes? Could I stack a fuel box with my Puck?
Thanks a bunch guys for the replies. I'd rather ask you guys than call a performance shop and talk to a guy on the other end that drives a ricer.

Sounds like you would be happy with a fueling box. You can turn it on to play and the turn it off to tow.
Most likely any fueling box will add 120 Hp, so you will not likely be able to use that much until you ungrade a turbo to use all of it. But most fueling boxes are "on the fly" tunable so you can determine just how much you want. Bigger injectors are "ON" all the time, might be a bit much for the HY9 when towing.

The Smarty is a fantastic product that does what it is is advertised to do. But I'm beginning to waver in my belief that it is the best for what *I* want for my particular usage.
I'd like to go from having a mild performing truck to a monster, just be flooring the pedal. But with my current setup, I feel like I am riding a skittish horse that is just begging for the chance to throw me off-- and more than willing to risk breaking his own legs to do so.
