Well, well. We finally hit on a subject controversial enough to get you to stop lurking and post.

Welcome - we could use someone with your turbo knowledge as an addition to the existing N/A brainbank.

My sarcastic point is this:

If you wish to add a powerflow to clean up your engine compartment and are willing to pay huge bux for it then by all means do so. This falls in line with my posermobile kit.
I just don't like the performance enhancement claims that the manufacturers make. The contoversy in this case is not how much power is added, but if any is added at all. If they wish to sell this item as an asthetic improvement I'm all for it. The stock box is an abomination. But it does work. Porsche engineers do a pretty fair job.
