Ok...got my $600 rebate check this morning and I'm buying either a scangauge or wideband... Mods are in sig, plus I have 3" o2 housing, 3" downpipe, agp cai, and mapclamp all in the mail on the way. At this point in time, which would be more beneficial for me as far as tuning? Some say the wideband for air/fuel, other say scan gauge for timing/kr b/c if they're good the air/fuel is good. Opinions please? Ordering tomorrow...
