Default So it appears I had a boost leak...Need some advice

I changed my cat out for a test pipe this morning and noticed that the fpr line wasn't looking so good so I replaced it. Went for a drive after I was done and am now boosting 20-22/23 ish. I'm a little worried about that much boost. I have a k04 and GIAC tuning for a ndbw aeb with a 5 bar fpr. I also have an intake and the test pipe. Should I install a mbc to turn the boost down a bit?

Wow, that's getting up there! What were you at before the test pipe install?

Can you VAG the car to see how lean you are in the upper rpm?

Default Well, I understand lazy. My K04 gets a little lean above 5,000 rpm. I really don't think your

boost levels should be any kind of issue for you. If you finally get off your dead *** later this week, you can verify this with your VAG. Until then, HAPPY BOOSTING =)

BTW: I think anything above 20 psi is getting out of the K04's efficiency range. You'll then just get hotter air and less performance. I don't know this for a fact though.
