[1k95gsx]

ok i put a full 3" exaust on my car turbo back with no cat my o2 sensor broke during the install ive had to drive it for about 4 days not being able to go over 4k rpms or it would bog down/back fire i picked up the o2 sensor today and disconected my battery to clear the code but now once i get up to around 4k it sounds like my bov is leaking any ideas on what to do?

also check to see if you put a gasket if your getting boost creep you will hit fuel cut at about 4000

How do you know you're getting boost leaks? Get a boost leak tester first.

i dont know if the boost is leaking as soon as the turbo starts to kick in it sounds like the BOV is alowing all of the boost to leak out its making the sound of the bov but while i punch the gas and not when i let off of it like it was its a auto so the bov lets it bypass when u take ## foot off the gas
