would a tune be required on a 2004 wrx? currently on a td06 20G turbo, mishimoto aluminum radiator and tomei exhaust with a gs boost controller no other upgrades currently. would this be overkill for the car when it comes to fuel? or will the ecu tell the car to retart the pressure of the pump?

A: Hello Niran, The DW400 will not be a direct fit into the 08-18 STI assembly. The physical size of the pump is much larger than the compact pump that comes in the OE assembly. Significant modifications or a different pump assembly/hanger design will likely be required.
