Did a basic tune to an otherwise stock 2016 3.7 Auto. Did TQ Mgmt stuff and added some Spark. Idle surges between 560-850ish. Car idled perfectly with stock tune. Played with Spark in MP0, changed IAT table back to stock. Still had the issue. Made a completely new tune with only TQ Mgmt stuff done to raise limits some. Still has idle issue with NO changes to a stock Spark tab. How can this be?? I've uploadee TQ Mgmt tune and logs.
