Its very rare on pump gas to get above 19 degrees,.... can it happen sure, but rare. These engines love being able to ADD timing, not so fond of removing it. So running a lower commanded number, and letting it add to it is always a happy engine :)
Is there a way to upload the log? It says it's to large.

It did stop at 19 I had some 18.5s in the middle and thought it was 19.5.

^^exactly. Should be tuned to a point where it can consistently add a couple degrees and will put a nice cushion if you ever get a batch of crappy gas.. I'm curious what is your WOT Lambda at on a WOT pull when youre experiencing the KR?

I don't have the data logs actually for that just my logs I made after I got it back from the dyno but I sent a message to the tuner to see if he can send me the spreadsheet. All my logs are after the boostane was added and fixed the a/c bolt touching.

Got cha. I haven't tested it on my car but I wonder if it's anything like some LS engines where too much fuel at WOT will cause a little knock.. I would assume it would not be that since coyotes seem to like running a little rich. Just was a thought and another factor to be looked over.

Maybe i know my afr is 11.5 at wot.
For some reason my car the ks pulled 2* on the same fuel another boosted car added 2* so I now live with 4oz of boostane per tank for safety. Tuner pulled timing and tried everything and said he doesn't know why as it should have fixed it by him taking some out but no matter what without boostane it pulled.

That's about .78 lambda which is totally fine. That's what I was running it at dialing in my car and had no KR. I'd be curious to see the tune and see which mapped points it's in when it's pulling timing. It's def strange and if octane booster fixes it, then it definitely sounds like the fuel..

Yea just weird though he put fresh fuel in my tank as it was basically empty for the dyno tune and said it was the same fuel he used on a boosted gt350 before mine and had no issues with it.. and said guess your car lives with boostane lol. I took it home and found the bolt issue and then added the boostane and it hasn't shown one spec of kr since . Just adds up to 4* now and now I am putting in a rst this week and it's slipped ever since the boostane so I'm excited to see how it really feels to get a good grab on the clutch and go. What's your set up?

ESS with 120 pulley on 93. Since it got a little cooler out my car likes to run 17 degrees at WOT. Must have good fuel in my area LOL

Shrader said charlotte just has crap gas especially when winter comes in. I would like to move it to 17 but tuner not comfortable doing so and wants me to stay at 15 and keep it a safe tune. SO I just emailed him seeing if could go to a 3.6 and a boss im. And still keep it on a safe tune To bump me up 50 675 really is my goal just shy of 700 and keep it there till I save up a bit more for supp mods and then I'd like to hit 750.

I personally don't give a crap what my timing is when I'm boosted. I can't tell much difference lol. If I was n/a its more noticable. My car was adding a lot so I just bumped it up a couple degrees and it still adds timing to get up to 17
