I need to know which to use. The setup to be on the car is fp20 invidia tbe, invidia up pipe, tial 38mm wastegate, sti pinks, 255 fuel pump. I dont think that any of the other mods are going to matter. I just need to know what you guys have had the best luck with. Also Shiv will be tuning the car. Just doing my homework so that I know what to get before I go. Thanks in advance.
