EFI Boost Regulator Prostar Black

The EFI Boost Regulator Prostar Black is a precision fuel pressure management component engineered for modern EFI fuel systems running boost applications. Built by Magnafuel/Magnaflow Fuel Systems, this regulator is designed for engine builders and tuners who demand reliable fuel pressure control under forced induction. It is suitable for turbocharged, supercharged, or nitrous-equipped vehicles, ensuring consistent fuel delivery across varying load conditions.

This regulator compensates for boost pressure in real time, automatically adjusting fuel rail pressure to maintain the proper fuel-air ratio as boost rises. The Prostar Black design integrates seamlessly into 1/8" NPT porting typical of modern EFI fuel rails, allowing for straightforward plumbing without extensive manifold modifications. Its compact dimensions and lightweight construction facilitate flexible mounting in tight engine bays.

Serious tuners and street performance enthusiasts will benefit most from this regulator when paired with a quality fuel pump and closed-loop engine management calibration. It is ideal for LS, modern Mopar, Ford Coyote, and other aftermarket EFI conversions where OEM fuel systems lack boost compensation. This product is a reliable choice for those looking to enhance their vehicle's performance under boost conditions.
