Sevens are like women: sometimes you just want to call it quits but you can't imagine your life without them.

About a month ago, i fixed a leak in the Y-Pipe coupler. Afterwards the boost pattern was 10-8-10. About a week after fixing the coupler, the boost gauge needle started bouncing around anywhere from 6-10 psi from 2K to redline. The kick around 5K is still noticable but not as much. I've already read http://www.autosportracetech.com/RX-...leshooting.htm, but was wondering if any of the gurus could narrow it down.

THanks for your help in advanced... i must go deflood my car now.

 

I suspect it's a clogging cat or another boost leak in a different place. Or maybe a boost leak in the same place, if something is rubbing to abrade through it.
