    The mode your ECU goes into when at WOT wont be affected if its been reset or not. It wont change any of the values at WOT. Maybe your MAF was dirty.

    Cton, but when I just drive normally, I can feel the car producing alot less power, like I mentioned before that the rev would go really high but I don't feel boost, it's like driving a NA car lol.. maybe the ECU was already noticing something different, but no CEL till recently..

    WOT is a preset tune in the ECU. Regardless of mods, the car will still run the original base tune.
    On part throttle, the ECU sets/adjusts values with LTFT and STFT (long and short term fuel trims)
    Resttting the ECU will only reset the LTFT and STFT.

    It was most likely caused by crap in the fuel and a dirty MAF sensor.

    I've tried the resetting and not resetting the ECU and the difference can't be noticed.
