Current set up is...TFS heads, TFS stage 1 cam, Edelbrock Performer RPM II, and BBK full length headers. I have a 255lph pump to install along with a adjustable FPR. Second, will my stock injectors be able sustain the added power from my mods? So what i really want to know is..is it worth it to have the car tuned and dynoed or can I install my FPR, adjust it and go? Any help is greatly appreciated.
