Siome engines don't like it and with throw up the management light. I woudn't bother on a standard car. Too much hassle for very little difference.

It improves throttle response in my honest opinion

Heres another question for you all. Ive seen on ebay a n249 bypass valve is it better to use one of these or to bypass it using the method in the thread by BaV using just 3mm pipe?

If its still a recirculating valve it will work. You don't wanna be dumping to atmosphere on a 1.8t.
