I would make sure your pressure reading is accurate. When was the last time it was lower? Did you make any changes to the unit? Good news is that it seems to have a low TDS. By the way, I'm assuming that the pressure you're measuring is before entering the system?

You might have issues developing leaks with 120 psi.
My house has 120psi and I developed a leak in my ro/di bypass valve (not sure it was caused by the pressure or just a faulty valve) so I got a pressure reducer to run at ~65 psi.

I haven't looked in a while, but I seem to recall the recommended max pressure for some RODI units being around 80psi. 120 household seems crazy high to me, but maybe that is normal some places, like if the 50 feet of head from a water tower is in your backyard 
The max pressure code allows in residences is 80 psi.
The weakest component in RO systems, in terms of ability to withstand high pressure, is the filter housings. Max pressure on the clear housings is typically 80 psi. You are risking one of those blowing apart under high pressure.
You need to either:
install or adjust your whole home pressure regulator, or
at least install a pressure regulator on the tube feeding the RODI. https://www.buckeyehydro.com/pressure-regulator/

My pump brings my pressure up from around 50 to 105, it's been running that way for years. I agree, 120 does sound too high.
That is probably OK, AS LONG AS your pump is AFTER your prefilter housings.

It isn't, or actually I don't really know. It's the aquatic life smart buddie booster. It has six input/outputs. I'm sure where the increase in psi happens, but I measure it before the RO membrane. I may have to start measuring in other spots just to know lol...

120 is some Rambo getting the fire hose pressure.
If your whole house is getting that, consider talking to a plumber about a PRV for your house. If your house is PEX it doesn't like much above 150 to 200 PSI. PVC can handle 300ish while type L copper could probably handle around a thousand PSI. But it doesn't matter at the end of the day. Your dishwasher, all your faucet gaskets, stems, etc. Don't want more than 100 PSI.

It’s not that my house hold is getting 120 
.. my house hold pressure is about 50 psi.. I have a 4 stage 50GPD REEFPureRO, booster pump is HF-8367, fitted between sediment and carbon block filters.. no leaked in tubes, my concern is if I’m producing bad water sure to high pressure..

Since you measure 0 TDS - it would be difficult to make 'bad water' - unless your TDS meter is wrong. There are 3 simple choices. 1. Your TDS measurement is wrong (doubt), 2. Your Pressure measurement is wrong. 3. You have too large a booster pump for your system. Oh - and 4 - sorry - there is a plumbing issue with your system
I don't think the OP said he uses a booster pump
Ugh. Not a fan of those things. They take standard parts, and seal them in a case so you can't get to them/adjust them.
80 psi is the max pressure in residences (per the plumbing code)
I think what you have is an imported booster pump that can't be adjusted. Call the manufacturer. I wouldn't allow this 120 psi situation to go on - something is going to fail catastrophically.It’s not that my house hold is getting 120

Low pressure, more wastage
