yeah i replaced my injectors in my 78 300D about a month ago...no siginificant change from the original ones only except i get a little bit of clatter now at lower RPMS but runs a hella lot smoother at +50mph...less sound. i used the heat shields supplied from the bosch rebuilt box from the ones that i ordered ( brass ones) i dont think it makes a difference at all..

anyways, is it good to do an injector pump timing when changing these bad boys out?....perhaps thats whats causing my poor 300D from smoking more than what it was before with the old injectors?..
