I have usesd Superchips products supplied by Troyer Performance since 1997. Unless you compare a Superchips to an Edge or Gryphon product with the same vehicle you will never know. I have compared Troyer to Hypertech with my truck. Night and day difference. I have also compared a local tuner to Troyer with both using Superchips custom tuning on my truck. Night and day difference. That is why I am still using Troyer Custom tunes but now with an Xcal 2.
