Let me be the donkey to find out

But I dont have a clue wich hose to pull of and close of.
I would appriciate it if I can get some clear pictures or a clear how-to :wink:

Disconnect either the vacuumline or electric connector and it should stop working.

Depends if you want them stuck closed or open.

open offcourse

But I've disconnected the T-vis connector now.
I do notice some loss on low rpm torque, but now when im driving at 4000/4500 rpm steady and I floor it, the response is much better!

Before this, the t-vis needed about a second to open or something like that. Now it just goes when i put my foot down at that rpm range.

Now i need a driftday to find out if 3th gear drifting goes easier.
Last time when I was in a second gear drift almost in the rpm limiter and i decided to go to third gear, the revs went to just the point that my t-vis closed for a moment. At that point I got in a noticable powerband dip and the engine just dropt dead so ik had to shift back to second.

I think that's also all over now, because i dont have that dip anymore.

Dwars,

if you're really tinkering with this, get yourself another Tvis plate and take out the butterflies all together, then install that in place of your current Tvis.

That might improve things a little as well on the high rpms. Even when stuck open these butterflies still form an obstruction.

I still have one of those butterfly-plates in my shed. So if you need one...

how much?
