Air Cleaner Question

I have a 2000 F350, DP,Ford AIS filter w/fender boot, exhaust is stock except for a 4 in. Muffler.
The AIS flter did not seems to help any and I have had it on for a year or more it has a new filter in it. My Question is the other day I removed the filter and drove it for a couple of miles( I know Bad Idea) but it just has never seemed to help. But the truck ran alot better with no filter in the box. Any ideas why? It just seems like I have lost milage and power with the AIS. I have tried it with out the DP and at different settings.
Just thought I would ask. Thanks AL

If the boots were loose, taking out the air filter shouldn't make it run any better. I would order a 6637 filter form www.fleetfilter.com and see how that works. It is cheap and flows alot of air. You could see if that helps or not.

The airflow through the AIS and 6637 are fairly comparable, if I remember correctly.
