Actually, the dcis win at dyno only. Irish tested them until the numbers stabilized. single passes typically show the dci winning on the 1st couple of passes, especially with hood closed. Once things get hot and the temps stabilize to the conditions, the oem box wins as it draws colder air.
I showed that at the track on stg1 the dci performed worse.
