Just installed a greddy oled boost controller and having issues with boost dropping off instantly. s13 sr20det with brand new s15 spec r turbo installed a year ago. new plugs and coils couple hundred miles ago. stock ecu stock injectors. not looking to raise boost level just the quicker spool to boost level. installed boost controller per instructions. tee'd in controller to line from top left port on intake manifold to fuel pressure regulator. top right port on manifold is ran to BOV and a tee to boost gauge. bottom port on manifold is capped. hot pipe pressure source to port 1 on solenoid and port 2 on solenoid to wastegate. set % is 0 tried every gain setting. start boost 8psi. hits 8 psi around 3000rpm then drops to 2-4psi then as the revs climb boost continues to climb to around 8 then will drop again. did a boost leak test and found a couple fixed and problem still persists. any ideas what the issue may be
