get it maped mate or it will go bang
your ecu is maped for a 1.3 n/a factory spec
your car is noway near standard
when ed was showing me the diffrent maps at JAE the main thing i noticed is that n/a fueling is a slow increace with rpm were turbo has a drastic increace in fuel
so your right that your car is not overfueling
its probley running really lean when the turbo kicks in
