Message	Hi guys, I am installing some HKS wastegates on my s14/rb26 project and am curious as how to set these actuators. While searching, I commonly found most people set their actuators to about 2psi higher than what they want their target boost to be considering exhaust gas pressure and pressure drop through the intercooler. Is this when the wastegate first cracks open or fully open or some other point? When I was playing around with my actuators (compressor w/gauge), I set them to about 15psi for when they first crack open, but then I increased the air pressure to the diaphram to about 20psi and the wastegates were only about 1/3->1/2 way open. Is this normal? AWD RB26DETT 1998 240sx SE
