sorted air leak but car wont accelerate properly starts popping code reader brought up coolant temp sensor could that cause this problem or could it be the n75 boost controler valve car has never been remapped and is boosting at 9psi
if it flags a temp sensor problem up again after clearing the code then I would start there, if you check the measuring blocks you can look at the ecu temp sender in real time see if it looks obviously wrong compared to the dash temp display
