personally,,and idont know whocares but,,,as far as the kkk vs. garret debate,, ,,ive ran both onsame engine,,and my basic impressions are : kkk turbo,,good low end+midrange,,falls off uptop,,,,,,,,garret,,ok low end,,midrange better,starts coming on strong,,, topend better punch than kkk,,,,,,,,,,,,,,,,,,,,anyone else think they"feel" like this????i chose the garret for the tdi,,,,,,,,,ok the kkk was stock on the 84 td jetta,and the garrett was from an 86 jetta td,,not an eco thingee or anything
