i just recently had a ko4 kit with giac software installed on my 99 a41.8t. i have about 90,000miles and i am on the stock bpv. i have no idea where the **** my boost has gone. do you think that the bpv being old and warn is the problem if not what do you think? i purchaseda forge and i am waiting to install. thanks

Yeah, that sounds like the first thing I'd check/replace. You may also want to inspect the clamps between your turbo outlet and throttle body, since your K04 install was recent & there may be a loose clamp?

thanks. i am told by some people that it may be a hose leak..?

I'm thinking about modding my car but I would be starting at 100k miles, I was wondering if you stared to run into issues with your car. As for you issue I would get a new BPV. I hear they have a hard time keeping boost with chipped k03's. Could just try a TT valve if you dont feel like spendng money
