    Fuel trim normally means you have an exhaust leak or downpipe leak before the 1st lambda sensor distorting the readings. Hence the fuel trim.

    Op if you have an aftermarket exhaust on, or even if it's stock I'd check the v band clamp. Maybe warped and need replacing. This solved my trim code.

    If its cutting out I'd look at the maf sensor. Find someone with one you know is good, swap it and see if it stops it.

    Could issues with the maf cause boost issues?? See ive watched the boost gauge an im struggling to boost over 5psi an normally hits around 15psi but aint got any error codes apart from fuel trim

    Yes definitely mate. It's essential to be in working order so it can interpret the airflow and adjust the air fuel ratio properly.
