I would take a remapped ecu any day over a piggyback, i feel its a much safer and better way to go. A piggyback it seems like its fooling the stock ecu to think its running stock but the output of the piggyback adjusts a few sensor to get more power. In the audi/vw world we only did ecu flash's no piggybacks. 1 advantage i see with the piggyback is you can remove it and go to the dealer on a stock ecu.

Thank you!!
