I'm having difficulty with my Predator and I'm looking for opinions, help, and others that may have experienced this issue. I have a 2010 R/T auto. The car is bone stock, no other mods but the Predator. I'm in CA, so the best fuel I have available to me is 91 octane. I've tried out the 91 Performance canned tune with a tankful of 91 octane, and I'm getting audible knock at part throttle, below 2000 RPM and below 20% throttle, and I'm seeing KR of up to 15 degrees when I hear it ping.
I'm seeing no KR at all on the stock tune. On the stock tune, the car is fine, runs great.
After the first tankful of fuel I tried, I ran it out and filled up at different station, different brand, but I'm experiencing the same issue on the 91 canned tune.
