I was just looking on the airflow meter I got with the RB25DE engine package and it has a spot like the RB30's Bosch AFM where it has a mixture adjustment screw. The Skylines AFM just has a deeply recessed blind plug in the side. Is there any provision for mixture adjustment if need be?,or is the computer and O2 sensor flexible enough to adjust mixtures over a wider range than the outgoing VL setup? This would be good as the car won't have to be touched as much.
