I've been logging and setting up my scanner for the Gen V stuff, and I noticed I'm getting midrange RPM KR on the stock tune. Motor has a little over 100 miles on it. After looking at the stock tune it's pretty clear the engine is reluctant to enter PE from 1700-3000ish RPM. The PE table is also really lean between those values. I'm new to this direct injection stuff, but the PE tables makes me think this thing is way too lean and too strict about entering PE down low.

KR is very common on stock tunes..
All GM v8 vehicles are reluctant to enter PE so nothing new there

If you don't post your tune and logs when you have questions you aren't helping yourself.

My c7 pinged audibly on the stock tune on Shell 93. It had to go.
