ok guys, I need some input. I already have an intake, downpipe, and exhaust. What should be the next step I take? I know that I am going to need to replace the clutch soon-that seems like a pretty standard upgrade in the beginning for our evos. Before that though, should I do boost controller? safc? any input is helpful

 

s-afc to mazimze the air flow or get an upgraded ECU, I got my s-afc from buschar with all the good settings makes a nice difference.
