Steve, I think I see your point. My well is 180 ft deep and pumps another 75 feet higher after it leaves the surface. I had the 1 hp pump put in service about 1990. The PVC tubing string was changed because of hair line factures caused fron the pump torquing the tubing. It should have not been used in a well anyway.

At any rate, you must have a bladder type pressure tank. Again, I have got 25 years of service from one. If the pressure in the tank is decreased, the pump kicks on more often. There is a point where adjusting the tank pressure and the relay won't go any lower. I have had mine down to off at 30 psi and on at 20 psi. With a full stream of water, the pump is on 25% of the time.
If I put an auxillary pump on it, I'm thinking it might collapse the tank's bladder. Could be wrong there. The kWh usage would probably go up unless it's a super efficient pump.

I check the pressure tank pressure at least once per year and keep that up to specified pressure. IMHO, that's the major reason the tanks go bad. The bladder expands to a size that streatches the bladder and causes undue fatigue. The second reason for failure is undersized tanks. I buy the largest ones I can find. If the pump is constantly kicking on/off, it will wear the entire system out much faster. Also, the larger the tank, the less chances of freezing too.

I have been wondering if anyone has tried using nitrogen in these tanks? My truck tires love the stuff.

I hope this helps.
