Whether your car is chipped or not, I highly recommend this product in order to maintain the health of your turbo. Although I don't have a boost gauge installed, I can feel that the turbo responds much better than the stock setup. Other than removing the air flow restrictions placed by the oem pcv, another advantage is that it is now conveniently placed under the hood providing ease of checking/cleaning. Also compliments the BSH intake very well if you have it!
Installation may be a bit advanced, and I suggest getting a profesional to do it.
