In short: Fuel pressure regulator with higher pressure than stock unit to allow increased fuel delivery.
For whom: For those who wish to extend the limit of their current injectors or for injectors rated at higher pressure than 3 bar.
Details: Fuel pressure regulator, replacing stock unit. Base fuel pressure is 3,5 bar instead of 3,0 bar. Fuel pressure then follows boost pressure linearly, i.e. 1,0 bar boost pressure means 4,5 bar fuel pressure. 100% bolt-on. Only fits on cars with T7, i.e. not compatible with T5 cars. NB! Requires modified software to function properly!
