Default 2002 wrx boost fluctuating

Hi all picked up a 2002 bug eye wrx the other day, felt it was pulsing when in boost so installed a boost gauge temp to see what was happening... The vid shows it all. Only mods are hks BOV and a stainless turbo back system and uppie. Any advice is greatly appriciated

Bad boost controller could do that. Try going from your compressor housing to your waste gate actuator directly and run off your waste gate spring. Watch the pedal though!
