I think by removing the secondary spring your removing what GFB calls the TMS advantage feature. Basically what makes it more responsive than a regular DV (or so they claim) If you remove it, it will make the DV act as a regular Rev D just probably more durable. Also some people get a soft P2261 code with the secondary spring in. I have a DSG and leave both springs in.
Alright, thanks. If they say it acts like the stock DV with the spring out do you have any idea if that would mean the flute or goose honk sound would re appear?
