[s-cars] Wastegate spring tightening

[Pasqualoni, James E]

Hallo Herr Maddock,

I purchased mine at TJM Motorsport
(http://www.tjmmotorsport.com/store/customer/product.php?productid=30581&cat
=728&page=1) for $90.  I did not make any ECU changes when I installed the
K-valve, as all it is supposed to do is allow the WG to cycle faster,
meaning the WG is now doing what it's supposed to at the right time-not
allowing over-boost.

HTH,
Jim

Jim,

Where do we find these K-valve WGFV's and more info about them?  Do they
require a motronic software change?

I want to replace my WGFV as I am still having intermittent over-boosting
problems, and this might be a good way to go..

Cheers,
