Ok i have a turbo kit ready to go on my si. I have everything but a tune. Should i go with a greddy e-manage or with the hondata s200 w/ the boost option of course. I know with the emanage you can hook it into your ecu and its already like street tuned for like 8 lbs of boost does the hondata work the same or do i have to tune it? If so how do i do that?
