i modyfied all map to value 1.0000
theoretically when change to open cone air filter has not restrictions as the stock air box with snorkel
as say vwaudiguy, logging and adjust
I wouldn't call it a "restriction" as much as different velocities/ airflow when compared to the stock airbox (which is, in most stock turbo cases, superior in my opinion for many reasons). Are you seeing lower IAT with the cone filter? Just doing it for the sound? Bored with life?
