most effective method of fuel delivery
 

Hi,

I'm looking to upgrade my fuel system in my FD. I was wondering which methods you recommend. Upgrading existing injectors or addding additional injectors? Using a whole new programmable ECU like the PowerFC or using additional injector controllers like Greddy? Also, what are the differences between a TVVC boost controller and an electronic and which do you guys recommend?

I'm looking to keep my stock twins with all bolt ons but keeping my options open to install upgraded twins if my stockers fail.

Which do you guys recommend. Thanks.

Ed

powerFC+rx7store fuel system upgrade = $2300 about
