I already have a tial mv-s ewg and yes i did feel that sudden lack of power. I was shifting hard from 3rd to 4th. Target boost is 18.5 psi, but, at the time the AP read 19.8 psi when it happened. I dont have access to adjust the cycle myself and if i do idk how. Im new to subarus and i bought the car with all my mods on and tuned already. I cleared the code and reflashed the ecu with the same tune. Can this have anything to do with my wastegate spring at all?
