Hi new owner to a Subaru Wrx Sti type Uk Hatchback
It had a fully Forged built in May and only covered 2k runinning miles.
very pleased and had to change up the wheels to personalize.
I also had this issue so had a 3 port boost solenoid fitted with the pipes all connected correctly and now car drives as it should no overboost as I suspect it felt like.
