I know when the PreCat is clogged that boost tends to be low. Any other things that I can watch for without physically taking it off? My idle in the morning is just barely rough, but always smooths out after driving. Also, Im only running 5psi on my secondary still havent found out the culprit. I will be getting a DP in January but want to know if the PC is to blame,

 

i wouldnt think the precat is to blame.

if your precat were to blame, it should have affected both the primary and secondary. not just the secondary.

my guess would be some kind of a problem with the vacuum hoses.

if your precat is clogged your car should feel restricted when you press on the throttle. your car would run much hotter than normal if the precat is clogged-and this is a major cause of rotary engine failures (so if you think its the precat get it fixed asap).

 

Check the CRV for the low secondary boost.

 

When both my pre and mid cats were clogged I was getting 2-3 psi, but not sure if it was on both primary and secondary. Like said if your primary is working fine I would look elsewhere from the cause of the low boosting secondary.
