i cant remember if i cut some bits of tube mate ? some more pics here http://micra.com.au/community/message.php?messageid=69926
and i,ve been running the SR t/b and cutoff stock maf on this current high comp engine for a while now 
edit, i think the leanouts were because of the very different shape/characteristics of mani personally, because my current SR/CGA setup runs fine
