with t-jet turbo you can achieve max 152 ps ( 135-137 ps wheels)....it's the maximum turbo limit....nobody t-jet owner here in greece,achieved 160+ ps,......also one reason which i prefer abarth's turbo is because i can achieve 182 ps without exchaust modifications...only a remap and that's all....its straightforward....a second reason : the abarth's turbo pressure, is lower 0,1bar in average from t-jet's turbo,this is an important factor for the engine-life.... a third reason : the cost of this modification is relatively low....(max 1500 eyro )
