will disconecting my egr valve on my furby vrs inprove performance any? did it on my old d turbo and it did inprove things a little.

you can turn it off as it is part of the intergrated engine electronics on the Fabia. It does not really improve the performance though, just increases the emmissions as they are not being reburnt in the engine. I've tried it, did not notice anything different and put it back on.

I reduced it by using Vag-Com. Never noticed anything. But in the long run should help.

Rooboy did mine and it didn't make any difference so I got him to switch it back on.
