with the antilag unit i have in the book that it comes with it, it clearly states "that prolong uses on the antilag system will reduce the turbos life"
i have yet to try my system, as when i bought it i was running stock ecu but never install it then i bought an pfc and install it but it fail to work, so it was sent back to GRiD in japan where they are rechipping it to work with the pfc
