Defueling is a safety feature that reduces engine output based on certain parameters. If your truck is stock it will defuel at any of the following setpoints:
  • Coolant temp > 227 deg F
  • Oil temp > 254 deg F
  • RPM > 4000
  • Speed > 95 mph

I know some tuners will allow you to change the defueling setpoints. Not sure about the Banks Edge but you can probably find out from their website.

yes u can set the defuel based on your EGT's with the edge, but seriously as someone who used to have the edge then switched to the sct, dont make my mistake...forget the edge start with the SCT and go get some gauges. If you want smoke give eric at innovativediesel a call

+1 on that. dont use off the self tunners with these trucks. (ie...banks, bully dog, edge, super chips) they are not good for the truck. use SCT with custom tunes from eric, or get a phanlax from matt at spartan diesel.
