Thats why now i am going to do some changes to the ignition system and fuel system and then go for the tune and see what happens.
what injectors are you running? I had the same issue for a while, and it progressively got worst and worst. Before i would clear the code, and it wouldnt come back for a while, then it started happening every time i started the car even after clearing the code. It was doing it when i had uprev and when i had ecutek. Problem went away when i switched injectors to id1300
