Having an interesting issue with my 2018 Camaro SS 1LE. Had the car tuned a couple of weeks ago and I have been sorting out a few issues. The part throttle was a little wonky and playing with the throttle tables smoothed out that problem. I am seeing a strange problem at full throttle. The PCM is pulling 10-15 degrees at around 6,000 RPM at full throttle. It's not knock retard. No matter if I am running 21 degrees or 25 degrees, the same thing occurs. The only mods on the car are a Soler Performance throttle body, a Green filter drop in air filter, and a flex fuel kit. The E85 that I am getting at the local pumps runs about 78-80% ethanol. I have attached a screen shot of the datalog right before the problem occurs, and one of the actual issue occurring. Ideas?
