[Norfolknudger]

Hi all I bought my golf early last year and have run around in it happily until recently she's been modified air intake decat remapped to 212bhp when I first had her she had a small occasional back fire  but recently it's started to over fuel with plenty of backfiring and she also seems to be choking  under throttling and missing I've changed the airflow meter the lamba sensor as its been decated it only has 1 and I've changed spark plugs but still no joy so I changed the ecu clocks and ignition barrel ran loverly till she got warm then started to choke itself again can anyone help as I'm lost now cheers all will
