    Welcome to the Forum

    As your car is normally aspirated I would say between 8% and 10% so if your engine is in good condition it should be giving around 330bhp so a re-map will give around 360bhp max.

    If your looking for more then you will need to spend quite a bit more on mechanical upgrades
