It sounds like you need to tune your serving lines.
Beer should be served at the pressure needed for it's co2 volumes at serving temp.
For example a beer at 2.5 volumes needs 12 PSI at 38°.
A Belgian at 3.5 volumes needs 22 psi at 38°.
Both have to have different beer line lengths to do this.
Beer lines will have a spec sheet from the maker that tells you how much psi each foot of line will hold back. The goal is to have about 1-2 psi at the tap.
Most 3/16 line will hold back 1psi per foot. Larger diameters have less psi.
So, for the 2.5 beer you need 10 feet of 3/16 line between the keg and tap for 2 psi at the tap. The 3.5 beer would need about 20 feet for the same pour speed.
Beer hack: To save on buying a lot of line for different styles you can get 3/16 line to hold back more psi per foot with weed wacker line.
This is my beer gun line I've tuned for very slow fill with just 3 feet of beer line using two wacker lines inside. This will fill a 22oz bottle in about 30 seconds at 12 psi
