just think about it....on a DOHC, you have the intake and exhaust cam. a cam gear for each one,..like when you get them on N/A you usually set the intake cam about 2degrees advanced. when turboed...what do you do? i'm just gonna set it stock and one day when i feel good i'll retard it to see what happens and if it doesnt feel good i'll just set it back to stock.....all this drama.....no one knows for sure!?!? Come Jeff, Dr. Boost, all you moderators! help us out
