I have a problem with my octavia vrs, when i accelerate with my foot to the floor it seems to missfire or maybe lose boost not really sure what but it only does it once i have been driving for about 30 mins and only at about 2000 to 3000 revs.

However i can drive the car without flooring it and it would be fine any ideas

Might help, might not.
