how would a d16z6 feel if i were to have a bad exhaust leak from the turbo mani to the down pipe flange, before the o2 sensor? IM throwing no codes but my car feels like its constantly climbing a hill.. The turbo is creating boost just fine, its just feeling real sluggish..

 

Is it making the boost it should? My wastegate kept coming loose and I'd lose boost. I crack in the manifold before the turbo should cause a lose of boost. Anything after the turbo really won't matter.
