Hi... . . . iv`e just poped over from the VR6Golf forum, and i am interested in this subject.
I have a OBD2 so can`t be touched, but the other half has a 2.8 golf OBD1 TB, which i have just changed to a 2.9 TB.
Does this need doing to the 2.9? as you can notice the difference straight away on the 2.9 !?
What is the stupid lump of metal for? (inside TB)
