I hate to burst your bubble. but that cobbled together "setup" is not only counter productive to performance, but is also dangerous.
Both the exposed, loose foam and the "accordion" type dryer vents are both serious fire hazards. They are both made of highly flammable materials and have no business being in an engine compartment. The foam would ok, if it were inside an enclosed box or something, so it could never accidentally come in contact with the exhaust or other very hot parts.
As for the dryer vent, again, it is a fire hazard. It is also bad for airflow. It is a rough, constantly changing id for the air to move through. With all the ridges inside (from the wire reinforcement) it is likely creating a very turbulent airflow. This is especially problematic for the entrance and exit of the MAF. Your "ad counts" are probably all over the place. Basically, your probably confusing the hell out of the computer, as far as it knowing exactly how much air is going in. Also, as thin as that stuff is, its picking all kinds of engine heat, as the air runs through the hose, defeating the purpose of any kind of cold air intake. That is a very simple tube to fabricate in some more appropriate material. In fact, it looks like you could just use straight pipe/tubing, with a 30 or 45 deg rubber elbow at the throttle body.
