Hi guys so a mate from work has gave me his old tunning box from. His old 1.9PD A3. I haven't been back into work yet to see him but I can't find any real great instructions for installing it. Last one I installed was on my vectra and it plugged into the injector rail. This one  has 2 push clips . I've read that it's possibly plugged I to the map sensor. Can anyone point me in the right direction ?

My bad it's supposed to be *tunning*box in the title . Fat fingers and phones don't go!! I don't know if mods can fix it or not??

Somewhere near the front right of the engine. If it’s one of those fool the car thinking it’s cold and over fuel ?
