Leave the socks out.. I do. You can research oil foam vs paper element on your own. You'll find plenty of info on the subject that goes far beyond one individual and a dyno. I personally guaranty it to be a really boring read...
It's important to remember that the Uni-Filter is actually 3 separate filters; the intake socks, the pre-filter and the main filter. If you wanted to do a complete comparison you should run the Uni in all 3 formats. With only the main filter it probably would flow better than stock. With the pre-filter added you might be giving up a couple of ponies, but filtration is much improved and interval services may be limited to just the pre-filter...
