I have basically the same question. I'm trying the Superchips 93 octane tune on 91 octane fuel. But since I'm at 2200ft, I thought that I may be able to get away with it without running into excessive KR. How much is excessive KR? I was seeing a peak of about 3* for about a second or two under the most extreme loading. Under 98% of driving under various loads and rpms, KR was basically non-existent.
