Then personally i'd check the clearance on it. Reset the TB via Vagcom (or similar) then check for air leaks and hose clamps etc. IF the car is mapped then as you say, no harm in checking with the tuner. But if the car has developed the problem sometime after mapping than the map can't be at fault.
JBS map the car since sponsering him, but the car has been heavily modified well before that and been through many turbo setups and maps. My missus car (Not mapped, so that rules out mapping in that case) has also suffered the revving issue in the past, but again, the clutch switch was at fault...
I'm sorry mate, but the clutch switch has alot to do with the car revving while shifting. Unplug yours, and after a day or 2 the car will rev like hell when shifting. FACT.

Clutch pedal switch should cut fuel when the clutch is depressed, but if the switch is broken etc then the ECU dosnt know that your about to change gear. Not a mapping issue either as several people i know have mapped 1.8T's and they do not suffer the same problems.
Air leak is feasable as...
My car feels 90% better today after having a bit of a fiddle after comparing my throttle to my neigbours car.....
We discovered my throttle pedal movement was real stiff and jerky compared to his. We watched the butterfly in the throttlebody which was also jerky. So, gave the throttle pedal...

Tried a few other things today...
Hi, sorry to barge into your thread (well whole forum in fact). Anyway, did you ever get this sorted at all? I've had the same problem in my car (Ibiza Cupra 1.8T 20v) since i've owned it (2+ yrs). I'm absolutely stumped as to what it can be. So far i've:
Fitted a new DV
Tried reversing the...
