Thanks!

You can get an adjustable FPR from ECS Tuning ($195). JUSSNB and I are both running this, but I'm not sure that it was required. Justin dyno'd his car at different fuel pressures, and I think that he ended up keeping the pressure at stock levels (ask him to be sure).

Also, I think Rob K. is running something different for his FPR. I'm not sure what it is, but I think its different than the ECS FPR.

from a 1.8t. It makes it much easier to get a good idle with 550cc injectors. Sorry it doesn't apply to you guys. What's your reason for looking for one?

I got mine from ECS Tuning, and it ran around $200. Scott is correct in stating that during dyno testing, I achieved optimum output when the fuel pressure was set at close to stock levels. (44psi, IIRC...but don't quote me on that.) To my surprise, runnning lean resulted in NO power gains.<ul><li><a href="http://www.ecstuning.com">ECS Tuning</a></li></ul>
