I installed my boost gauge today and it rests at -20psi at idle, but when i do full throttle runs it wont go past 0psi
I have installed it properly off the fpr. Using the plastic wiring that came with the gauge.
Im pretty positive i have no boost leak because i had seafoamed my car and no smoke was coming from the engine bay, is there also another way to check for boost leaks?
Thanks in advance

Looks like it's reading vacuum but no boost.
Could be a faulty boost gauge or somewhere in your boost gauge piping there seems to be a blockage that is preventing the boost pressure from going to the boost gauge itself.
Trace back your steps and hopefully you should find something that is most likely the cause.
