I just installed a Donaldson on my two day old 02 and now I read on the forum under search section that Donaldsons do not work well with 02's some said pig rich and some said super lean...I do not understand, Haltech and others claim there filters rock on 02's why doesn't the Blackwing, Haltech uses the same filter media as Donaldson. So what should I do? Take the filter off today asap and reinstall the stock setup? After I installed the Donaldson the car ran awesome...Please need some info and help I do not want to screw up a brand new 02. Thanks in advance.
