welshbuddy Posted October 28, 2012 Share Posted October 28, 2012 Hey mate, you don't need a piggyback, standard ecu is fine. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 28, 2012 Share Posted October 28, 2012 I dont like banging on but a standard air box with front cut out (BFI) is a far better intake solution. And no the stock ECU is fine, they run very rich on full boost anyway. Quote Link to comment Share on other sites More sharing options...
