A few years ago, a aftermarket fuel pressure regulator (2002) was discussed, and recommended. It was sold by turbocity.com apparently. I am not able to locate the web site nor the fpr. Any idea where I can buy it. I'm in Australia. American web pages often wants more for postage than the item cost!
From memory this company stopped making this a long time ago. Unless there is something wrong with your FPR, a much better option is a PCV with an autotune, it’s an accurate way to get the most as opposed to a hit and miss affair of a higher pressure FPR.
