.. I'm running an Aqua Fx Barracuda -- My gauge sits about ~45 PSI ish... I have been reading that I should have a booster pump... The ones i have found so far are ~$100 or more.. Anyone have any cool work-a-rounds, hacks.. they have utilized?

you can get the booster pump with all the hookups for $80 on ebay or you can use a pressure tank

The Aquatec 8800, 100 psi pump is the best pump out there. Go with the 100 psi is what most of the RO companies recommend. In the winter this is what I use and my waste water production is cut in half and I push 0 tds at all times/

Your optimal psi is 80. in the winter the pores in the membrane material shrink due to cold water the 100psi forces the water through the pours reducing waste water.

..so I bumped it up to ~80 psi, an interesting observation is at ~80.. there is minimal flow of RO water, almost large fast drops... although I did notice a nice flow when the pressure dropped back down to ~50 due to my washing machine pulling water...

Every Ro/Di unit is different. Optimal doesn't always mean fastest gpd. Although it normally does.
Most manufacturers list the optimal pressure to run your Ro/Di unit to get the longest life(filters) and best water quality coming out of your unit plus the best gpd.
You should check with the manufacturer of your ro/di unit to see what they recommend

Ro manufactures' recommended pressure doesn't mean squat as the manufactures change filters in production very often depending what is available to them. The most important psi recommendation is what the membrane manufacture states.
