Short story. After my ej25 rebuilt i had idle issues, my subaru tech cleand throttle body and also he tightened up cam sprockets on the left side. Idle problem was fixed, but car lost 30-40 % of power, like i'm runing wastegate pressure.
Turbo spools, but there is no kick to it, it spools steady from 3500 rpm to 5000.
Anyone experienced it ???
