I do not have a manufacturers hand book (cant read japanese anyway!) I have noted that when first driving from cold that my "check engine" light has come on. This maybe because i have ventured into the world of BOOST before the engine has warmed up completely (Known not to be a recomended action). Does any body know if this light would come on if run up on boost before engine up to full temp??
Light never comes on after engine warmed up fully.
Secondly does any body know what power/performance is sacrificed when running on a "BLITZ" exhaust system with the bolt in restrictor in place ???

many thanks !!
