You can usually return those.
tried they said hell no

For cruising around and not in WOT 14.0-14.7 is considered stoich which is where you want to be, it just depends on if you use regular gasoline or E10 (which is what most stations tend to use now a days)
When you go WOT, you want to be around 12.2-12.6 on the 5.0. 13.0 is the max but not needed IMO.
For Forced Induction cars, WOT fueling will look more like 11.5-11.7'ish.
then I guess you learned an expensive lesson. Extended warranties are useless especially if you are modding.
you can cancel your extended warranty but loose some of the money.
this is interesting to read coming from a turbo 4cyl. is the 11.5-11.7 based off of 91 octane fuel?
i tuned for 12-12.2 and ran it hard and strong on NJ 93 octane fuel.
for my NA 5.0L if someone showed me a commanded AFR that was that rich I would immediately be asking questions.
well still plan on modding with frpp so it stays under warranty. my buddy at the dealer did the frpp procal tune. next will be frpp gears and they will install

If you loaded that bama tune, warranty is gone.
Well good thing you don't have a 4cyl anymore. lol
Was your turbo 4cyl running 11:1 Compression NA? Since it was turbo I'd say no.
The Coyote 5.0 likes to be tuned on the "richer" side when NA, it has shown the best results so far. Sure you can run it at 13.0:1 NA, but there hasn't been any benefit shown by doing this.
hehe it wasn't that bad of a motor =]
9.5:1 was the compression, so no, def not 11:1. I'm still pinching myself that the day has come where a ford V8 can be so good!
so again are the 12 AFRs being suggested for 91 octane? are the 93 octane tunes seeing gains by going a little leaner?
and 12.3-12.9 on a gauge calibrated for gas.
Depends. You could lean it out a bit to get some more power. 11.8 is fine and actually on the safer side for N/A but I would command 12.7 when I tuned my old 06 GTO and it had no problem. Then again, cam in block vs adjustable DOHC so there's going to be so many more factors.
My rule of thumb(like I said in my first post) is 12.5 for an N/A car. We're also talking about gas here. So a lambda of .850 if you're using any other type of fuel.
If you haven't already, read through this thread. KenB shared so much amazing information.
