honestly, who cares how it compares. piggyback systems are great and all, but most tuners want something plug and play so they can bring their car into a dealer and not get the hassle of warranty arguments. the aem fuel/air ignition controller also looks to need wire splicing... honestly anything that needs wire splicing shouldn't be over 250 unless you get at least 20 more horses out of an N/A engine that has been factory tuned a$$ backwards like the forte has. each gear seems to have it's own personality which makes no sense. I really wish someone would break the code and it could just be hooked up to a laptop and tuned with a program like HPTuners or Trifecta. Mind you, I am not knocking this piggyback product, it probably takes care of the random gear personality and gives you a bit more power...but, most people don't want to splice wires... then again we also have to accept the Kia market isn't as booming as some others... plus it's easier to tune cars that are already F/I.
