missfire at 5000rpms

[surfo]

Hi I have a Seat Leon Cupra 180 20VT with the mods you can see at my signature... well the issue here is that some how today just after fulling up my gas tank... I went out and 500 meters away I decided in third to give it a full acceleration... and suddently at 5000rpms aprox, it began to missfire (farting you can say hehehe)... so I pull the acelerator off.. and drove normal... then after a while I decided to give it another try, just to see if it wasn´t just a casualty, and it did it again!!!... my coils are new...
any ideas.. I tought it could be my turbo giving his life up after 85,000kms of pure adrenaline or maybe water on the gas, but why just above 5,000rpms?

i had same problem in my ibiza but this was at any revs in any gear just when i booted it. turned out to be turbo problems which luckily for me was still under warrenty.. good luck mate.
