Q.  What Is The Difference Between a Handheld Tuner and LSXEDIT Custom Tuning?

A.  The Handheld Tuners are a General Tuning Platform that Sort of Kind of Makes a Difference.  They are Generic Canned Tunes That Are Loaded Into Small Devices that Don't Tailor the Tune to Your Actual Vehicle.  LSXedit With TEO  Uses HPTuners Software To Create a Custom Calibration Unique For Your Specific Vehicle.  Not Every Vehicle is The Same, Every Single Engine Will be Slightly Different than The Next.
