tbf, i dont think it makes that much of a difference. probably jsut abit better throttle response and noise, but thats about it. Having a well serviced performance panel filter is probably much more effective.

Not exactly no but another question comes to mind. In addition to the two MK3 I also have an MG ZT 260 (The one with the 4.6L Ford V8  ).

One of the performance mods I've put on the ZT is to replace the standard Ford 60mm Throttle Body with a polished 75mm Accufab and gas flowed upper plenum chamber. The difference this made to the V8 was quite remarkable, mostly down to the larger diameter and hence higher flow rate than any fancy polishing.

It took the ECU about 500miles to adjust to the high flow rate but has been peachy every since.

Has any company ever made replacement TB for the VW range? If not what about fitting a VR6 ODBII TB on a 16v GTI?

Are the VW ecu's able to adjust like the Ford?

Thanks just interested more than anything else.

Yep, Spent a few hours with some burrs cutting the hump out and polishing the bore out.
Also matched the gaskets on the intake.(Along with maf housing)
Would not like to say what gains i got on the 8v but my car does go well with the usual A box mods and PF zaust to boot.
(Have done my mates 1.8t in a couple of tear ups (on his private road)
Would say that when i cain it a bit it does use more fuel! (a lot)
and i get the odd pop on overun
Full head off port session would pay off better
