Primary purpose was to "tune the Tahoe" for towing.
Setup instructions could be clearer: 1. Downloaded setup SPARK went to UPDATE got error "Do not have updates for your vehicle" Call 888-.....Called tech said needed to plug into OBD II port get vehicle files. Got Stock files.
2. Got another message "Need to Charge battery first" Nothing mentions flashpaq needed to be charge?
3. Display Setting does NOT have a EXIT choice when done.
Felt the difference immediately on the freeway onramp!!
