always probable to have a leak of some sort, now that you have seen all of our hoses try to remember each one and which could not be sealing well. go over your vacuum lines and pull off your stock bov and try to blow through it. if you blow through it gone, if not well upgrade anyway. do you have stock airbox and exhaust on that? if it has the intake you will probably hear a 3 pulse flutter when you let off the boost.
i spent about $1200 on my engine and when i was done it was still stock. just extremely mint/stock perfect running nothing left to fix just upgrade. yea its allot and you probably wont go that far but i am anal when it comes to having quality parts under the hood.
