Close ICV for Boost Test?
I have maximum 3 PSI of boost, so looking for leaks. Sounded like something under the intake, so I checked the ICV.
When connected to the outflow of the ICV, with inflow open, I can't pull a vacuum. When I pressurize the outflow, I get noticeable airflow out the 'inflow'. Is this normal under pressure - should this valve be airtight? I've heard people talk about it leaking out the connector and from the o-ring under the metal housing, but not about through flow.

you need to do the LED test to see if the KLR is throwing a code.

I built the LED, it worked for a no-TPS test, but was often giving small intermittent garbage otherwise. Most of the time it reads nothing. I just put up a larger test thread here.
