Naturally your tank will run out quicker--and you will spend a lot of time driving back to the truck, refilling the tank and mixing new chemicals.
Suit your speed to the situation. Herbicides and insecticides 4 mph. Some odd product that requires four times as much water per thousand--just go 1 mph.
I want to be able to spray fertilizer which is why I want to spray the higher volume.

My question was just basically if it would be a good idea to go ahead and get a bigger pump than the 2.1 gpm.

The mechanic at the golf course I work at that helped me put the sprayer on the mower told me I would need one if I wanted to spray higher volumes.

Just thought I would ask some people with more experience.

Only after plumbing it with big hoses as well as proper pump size was I able to get that calibration. Therefore 2 gallon per thousand isn't wrong in my book.

BUT MY POINT WAS NOT ABOUT A BIGGER PUMP, BUT WHAT SIZE PUMP IS NEEDED TO DELIVER 2 GALLONS PER THOUSAND. I was trying explain WHY/HOW math is used to engineer and Design a boom sprayer. I am not able to get my point across because # 1 I might not be a Good Teacher or # 2 I don't have students able to understand the Ideas I present to them.

.
I'm gonna go with #1.

It is a whole nother ball game if you plan to apply fertilizer as a liquid. And do not want to burn the grass. More important if the temp is over 80. In that case you need at least 2 preferably 3 gallons per thousand sqft. So you need to drive real SLOW so you cover about 1000 sqft per minute, say 1 mph.

Do it right--buy a Permagreen Triumph. Weed control sprayed. Fert as a granule.

You will need the 3.8 gpm pump and 11004 tips...I use TeeJet AI 11004 air induction tips.

At a spray speed of 3 mph this is a spray volume of 0.84 gallons per 1000 sq. ft. or 36.6 gallons per acre.

Right that is 2 Gallon per Thousand just like you ask in your first Post.

I got my sprayer from tractor supply as well but I got the 15 gallon with only two nozzles. Do you still recommend the 11004 tips? I don't want to spray any wider than the 80" it already sprays and would actually like a tighter pattern. All the lawns I do are small with beds that I'll have to maneuver around.

Sorry...I assumed we both had the same setup.

I'm not sure exactly which unit you have but it sounds like you have the unit that has two FloodJet WideAngle tips. The FloodJet WideAngle tips are high volume tips and you probably won't get 40 psi with the 2.1 gpm pump.

If you are wanting to switch to flat spray tips, yes, I would recommend the 11004 AI tips.

That 2.1 gpm pump may be sufficient to get 40 psi for 2 X 11004 AI tips.

With 2 X 11004 tips set 20" apart and 20" high you will get a spray width of less than 4'.

You could add one or even two more tips to the boom but then you would definitely need to go to the 3.8 gpm pump which would probably have pump cycling issues with so few tips.

Try two new tips first and let us know how it goes.
