Every time I have set a personal best, it has been as the result of a hot lap. It is totally counter to all I have done for years and years...but these cars make power when they are hot.

I noticed that too. My car made its best pass two weekends ago on my 5th hotlap in a row. I was frustrated with the clutch issues I was having, and just kept going back in the staging lanes to get a clean pass.
FYI... I have life outside of my car hobby.
I am a full time student, matter of fact Double time student. (Taking 25 units in college this semester) so haha
Don't worry Shaun you might be seeing the head very soon. I just need time to take the motor out and take the heads off again.
sorry double post

Still... A month later... This...
I was there too, I put down 408/387 with Shauns tune, JLT intake, and cat deletes and muffler deletes
Here's a log from a Member on this site. Factory stock 2012 GT on the stock tune.
This is a 5th gear run and it shows the ECU commanding a lean A/F at WOT, then cat overtemp protection kicks in and richens the mixture. You can see the ECU is also pulling spark (likely thru Knock sensors) in an effort to save the motor.
Imagine if this was a tuned car with off-road exhaust. A tuner may turn off Cat enrichment since there are no cats, add some ignition timing and if it was a year ago, modify the knock sensors to not pull as much timing.....
Tuners made the problem worse, but they did not cause it.
WoW! I don't mean to bring up this old thread but after emailing Shawn today regarding his tunes and getting the confirmation from him that the #8 is in the factory tune I decided to take this info and do a little research myself and I can't believe my 4k miles old 2013 GT M6 is a perfect candadite for this #8 issue!
As some of you guys might know from many threads I started in the past I been trying to figure out why my track app and torque app are both showing 13.9-14.1 or stoich on WOT, and if these values I am seeing is just a glitch or very real. Now I know this is very real. My 2013 is commanding stoich on WOT!! Now it all make sense. I always wondered if my car felt underpowered on WOT and sometimes it would feel like something was holding back the 420hp on WOT. I always knew something was not right but with no CEL and the car running ok overall I just thought maybe it was me getting used to 420hp.
So have any of you other 2013 GT guys been checking your WOT AFR on your track app? Especially the manual guys. What I still don't understand is why are some cars commanding stoich on WOT from the factory tune? Obviously this problem is in the tune like Shawn have concluded. So how are cars coming off the factory line with stoich WOT AFR? I'm glad that I have the track app or otherwise I probably would have never known, not to mention, how many stock 11-12 GT guys that are running around blindly and not even knowing their car is running stoich on WOT and losing power due to timing pulled and COT.
What make this even worst is that my dealer where I purchased my vehicle from said not to worry if I don't have any CEL when I expressed my concern regarding my WOT stoich AFR
so does this mean the only way I can have my car running the way it should is with a tune that will void my warranty? I don't know what to make of this.WoW!
Pretty much.
So obviously my car is calibrated from factory to go stoich on WOT since my logs show that the ECM is commanding 1(14.1 for e10). What I don't get is, why are
only "some" coyotes seeing this? Supposedly, some people's are seeing the "normal factory" low to mid 12 AFR all day with no issue according to some of the replys I was getting on one of my threads that I started a while back regarding stoich WOT AFR. Or, those guys didnt know WTH they was talking about and every copperhead is programmed to command stoich on WOT?
Looking through more posts made by Shawn in this issue, it look as tho WOT stoich AFR is a purpose filled strategy by ford to have a better torque curve at higher RPM but the lean condition is protected via COT protection which dumps fuel to cool off the cats. Supposedly there are more reason to why ford decided to go this route.
So another question is this. Is this really normal and expected? Again, purposely tuned this way by ford? It's really hard to wrap this around my head and believe that ford really programmed stoich on WOT.
Does anyone know if procal fix this WOT stoich issue or does anyone know what AFR their ECM is now commanding on WOT after procal?
I'm glad I talk to Shawn:beer:, or I would of still been listening to some of these supposedly know it all guys and still thinking my track app had a glitch LOL:bash:

Yeah i think Shaun really knows his stuff and thats why anything ford makes will be tuned by him LOL!
i never trust the AFR measured in the torque app since its got the 100% gasoline 14.62 vs. E10 14.0 conversion from lambda to AFR. And i think that factory lean out starts at 15 or 20 seconds so you would not just see it in normal WOT conditons. This is all just based on Shaun's thread. The L&M thread also bring up this issue but say its not just 8, it could be that left bank in general thats the fails they see.
The track app show 14.1 calibrated to E10. All copperheads are programmed for E10. My obd2 datalog show the same on WOT and part throttle/idle as my track app also. Not sure about the 15 to 20 seconds either. Mine show stoich on WOT very frequently and it's definitely no 15 to 20 seconds. It's usually as soon as I WOT. Yes, and this is a 2013 GT with a build date of may 2013:??:
The truth is in the commanded EQ in the datalog which clearly show command 1 on WOT

mine was built in the may 2012 - and I have never noticed this issue. when i'm on the throttle hard, i always have the a/f gauge up and i pay attention to it.
This^^^^^ I'm trying to figure this one out myself. This isn't the first time I heard someone say their 2013 AFR is on point. When I see other stock coyote guys that have perfect AFR reading I really don't know what to make of it. Especially when my dealer is telling me not to worry about my WOT stoich.

If you want to know if it's been fixed or on not in your calibration go WOT in 5th or 6th gear from a low RPM and keep it there for 10sec....if it doesn't have a corrected calibration then it will transition to stoich....
I never installed my procal. I will most likely just go with Shawn's tune. However, I did speak with my dealership again today regarding my WOT stoich and they want me to bring the car back in next week to do more testing. I really didn't have any plans to go with SCT anytime soon, but I plan to just go ahead and have my procal installed then and I plan to keep it if my AFR get fixed. I might as well try it since I can't find a buyer anyway. I talk to couple other well known tuners today, I wont name them, but its kind of strange that some tuners doesn't seem to have any idea on some stock coyotes running stoich on WOT.
