I had my jetta chipped for 2 years. Over the past two weeks my boost has dropped from about 19psi at full throttle to 9psi full throttle. It feels like my car is back to stock performance. I checked for leaks and repacked my DV valve and nothing changed. No lights are on and no limp mode. Any suggestions???

Re: losing boost? Help (Alienex)

There's no ez sure way of finding the problem, but there are cheap solutions you can try. I would guess that it's prob a hose leak somewhere because hose leaks are VERY hard to find. Change the vacuum hoses w/ silicone hoses from hosetechniqe. Clamp them in nicely too.

Good luck.

Re: losing boost? Help (jettakev2)

I solved my problem. About a year ago I installed my boost gauge and used a tee spliter on the line that runs from the manifold to the fuel pressure regulator. The tee was a hair to big and I had to use some force to slide the hoses over the tee..... Back to the present day looking for a vaccum leak for hours and can't find any. I decieded to make sure the hoses on the tee were on tight. I noticed at this point they were really loose. Upon further inspection I noticed the hoses were split. The reason it was so hard to notice was because the factory hoses have a braided material over the hoses. Went to the store, replaced the hoses and I HAVE MY BOOST BACK! It felt like the day I got chipped!! The End.
