i hope that this helps anyone out there becuase if fixed my problem.
ok, so i had two well 3 problems that this fixed. I first noticed the lack in power when i was comming on the freeway and my car could hardly accelerate because it was windy(head wind). ever since i got the car it felt like the turbo was worin to hard at to low or rpm's. It would kick in and not really do anything. Also if you put the gas peddal all the way to the floor it would let off a little. The third problem is that the car wouldn't start one time and then when i gave it gas it died. All these problems were related to the fuel pressure regulator i went to thisvlworld and it said how to fix it. The part was 87 dollers. When i put it in the turbo kicked in an much higher rpm's and wasn't as loud. It also shifted and ran smother and quiter. Now my car will pass efferlessly. I hope this helps
