Stock 440cc 3SGTE injectors are good for about 280whp wide open. This simple modification raises base fuel pressure from 3 bar to 3.5 bar, allowing about 320whp from stock injectors.

The stock fuel rail has poor distribution at this flow rate. It's recommended to also get a ported fuel rail.

Works on Gen2 and Gen3 3SGTE. Gen3 will require a smaller return hose.
