Anyone heard of "Powerboxes" for Diesels ?

[kippax]

I am trying to get some extra performance out of my co car a Lexus is220d (Not as easily done as a VAG diesel)
I have found these on ebay http://cgi.ebay.com/ebaymotors/Power-Box-CR-Diesel... & as buyer has 100% feedback to date i'm considering giving one a try.
Has anyone had any experience of these things or have any advise? (Needs to be removable for servicing etc )

Thanks
H

The link is either wrong, or the item's been removed.

But if it's on ebay and promises the earth, it's not likely to do much.

If it was so good, why don't the manufacturers engineer it in?

Ebay + 'too good to be true' 'revolutionary' 'power enhancing' gadget = con.

Try this link http://cgi.ebay.com/ebaymotors/Power-Box-CR-Diesel...
