so i hav a D16Y8 turbo @7psi. orig. i was running a 255 Walbro and a Blox FMU. wich im not proud of. I finnaly decided to ugrade and im getting my ECU remade for the fuel curves for the 450cc injectors, and ill keep my 255 Walbro.. som people are telling my to get a regular FPR and som tell me to get a Rising Rate FPR...which one do i need or neither? if you guys are running a turbo D-series let me know what you hav found to hav the most MPG and power balance in a fuel system. Thanks!!

Good mpg and fast cars don't mix

If you are getting your ecu remapped it should be for the factory regulator. All the rising rate does is add fuel pressure as boost rises. So unless thats programmed into you ecu you dont need it.
