I know this is a commmon question and I have done searches. But still cant figure this out. The rex only boost to 5 psi. I have heard people say the throttle plates but how can you test it? There are not any loose vacum hoses or cracked couplers. BOVs are good along with the acuator. So what gives. Suggestion please.

have you had any work done to the rx7 recently? has it always been boosting to 5psi?

Check the IC tubes, they tend to bust and leak out the other 5psi...

when I didnt have restrictor pills in the turbo lines I only got 5 psi too. Check those too.

What are pills? Are you guys talking about the check valve?

Thanks
