As you continue to tune, and I’m still working this, be aware that if your tuner changes the stock throttle table, it might cause the GM ECU to throw a P0606 code....ECU failure. I am currently experiencing this issue. Now it could be a legitimate ECU failure as well.....I don’t know for sure yet. I have had four tuners and my stock tune is no longer available for comparison. Glad the ring worked out.
