rite guys,little bit of info needed
my car didnt make any more power from .9 bar onwards,so the car was looked over and the out come was the back box 2.5",rite so iv bought a trust 3" back box,i also fitted a 60mm wastegate at the same time,
i put my wideband on the check it wasnt going lean from fitting the back box.
its gone the ather way,its really rich,b4 i had 10.5 afr now goes to 9 then the r for rich shows,(teckedge wide band)
so people does this mean that the trust 3" back box iv just fitted is more
restrictive than my 2.5" back box,as its showing its rich,

Probably means that you had slight exhaust leak before which showed a leaner afr on your wideband.
Is your boost still at .9 bar or has it gone higher with the new back box putting you in a different row of the map? Also can you list your full setup spec.
i did have one,il put the old back box on and see what afr i get,
that should be a little rich 2 as it was blowing b4 and not now.
