A quick update.
The shop tuning my Mustang GT is Alternative Auto in Chesterfield, Michigan which is a small shop and the owner is Lidio who has been tuning Mustangs for 29 years. He has my car done. His friend wiped the CPU getting rid of the Livernois Motorsports tune. He said the car was seriously lean. I asked him if that same tune or a similar tune was on the car originally would it cause the failure. He said very likely. He found an issue with the Magnuson vacuum line had some sort of blockage which effected the tune. He tunes for only one octane and I told him to tune it for 91 octane. He has and said I might be disappointed as the car dyno'd 530 rwhp. The car will shift at 7,000-7200 rpm.
I asked him about the tune and he is loading the stock tune on to a memory stick. He said that it can be loaded on to an N gauge, if I wanted to have it tuned by some other tuner. I am unfamiliar with this "N gauge".
Another thing that is irritating is that he could not understand how the car could have been given to me that lean and poor running. His comment was "it really ran bad". I explained that they had the car several times over several months. It ran bad every time. He said he thought the tune was "aggressive".
He said that he is friends with Dan Millen, one of the owners of LMS there and did not want to say anything bad, but that something is going on in their tuning shop to have these issues.
So, I will pick the car up when I get down there on Thursday.
If LMS is reading this, please refund my money. I can't get the summer back but I am not a happy customer and have been more than patient. $15,600 is a lot to deal with 6 months and hassles like these.
OMG WHAT ARE YOU DOING?!
You have a guy in your thread with a Palm Beach tune (TOP 3 in World if NOT #1 for S550/Coyote) with your same setup!
CALL Palm Beach Now!!!
You are going to get a known working good tune based on a known working good setup.

I was making about 700rwhp on pump and stock engine. At 530 I'd be beside myself....

Keep in mind that every dyno is different. I just left a dyno this past Sunday where stockish Coyotes were making 340whp. Same kind of deal as the OP.....small shop, older dyno. Also variables like Redline, gear used, traction control all play a factor.

A very well running 2013 auto with an Edelbrock stage 1 only made 426whp dynoed in 4th spinning to 6500. Take it across town to the dyno jet, run it in 5th to 7200 and I am sure it would have cracked 500. Dyno's are tuning tools.


@GreenS550 hopefully your car runs well when you get it back. My advice would be to enjoy it for a little while then consider your choices. Magnuson, Livernois 2x, and now some little shop in Michigan.

Success leaves clues.....stick with people with a proven track record.

Regardless of outcome, LMS is now out on my list of possibilities for FI in the future. I don't think we'll ever know EXACTLY what happened, but based on the last 2 pages of posts I've made up my mind about them.
I'd imagine they have lost a lot of potential business from this thread.

Damn and here I was wondering who Jenny is and what she is wearing...doh.
Didn’t even notice name/handle.
Users contributions to OP/forum are of merit regardless of my unfortunate archaic and anachronistic use of ‘guy/guys’ as informal indeterminate pronoun as used with connotation in the sororal or fraternal sense with respect for the contributions. An epicene such as ‘they’, ‘it’, ‘user’, ‘member’ or the more informal ‘peeps’ could have avoided the anachronistic/grotesque use of ‘guys’.

Thanks again to @JennyStang posting regarding PB tune for OP’s setup!

Directly from Whipple`s website.......
The Stage 1 kit for 2015-2017 cars makes "up to" 750 FLYWHEEL HP. This is also on 91 octane which some of us are only able to buy out West. This is stated on their website.
The 2018+ Stage 1 is rated at 775 HP. Again, that is on 91 octane and it's printed directly on Whipple's website. Im sure with different SC pulleys, more power is possible. I'm simply restating what Whipple themselves have said.

OP...take the car to the track...at least once. MPH will give you a "real" idea on what kind of power the car has. As stated above dyno's are only a tuning tool and do vary greatly. Look at my sig - first numbers were on a Dyna-Flow, second set of numbers two weeks later no changes on a Dyno-Jet.

Here is an update. I really hope Livernois Motorsports is reading this.

Yesterday I picked up my car from Alternative Auto. The owner is Lidio and he tuned my car. Last week he had a Ford tech clear the CPU. From there he tuned it for a safe 91 octane tune. LMS had put the stock pulley back on at my suggestion as to make the car more drivable. The car made 523 rwhp and 434 rwtq. We discussed the car in detail and why the numbers were so low. Lidio said with 93 about 20 more rwhp. That is still very low. With the smaller pulley and headers "about 580-600". He said the day the car was dyno'd it was in the 80s. He put many miles on the car, and worked on drivability. The car drives just like stock. Excellent shifting and runs perfect.
He apologized about the work LMS did. I said "it's not your fault". He said the car NEVER should have left the shop. It was apparent the car was very lean and just ran poorly as soon as we went for a ride in it. I showed him the bad piston and he said it definitely was pre-detonation that caused the problem. No doubt in his mind. He said several times that he could not understand why LMS let the car go out this way. That there are good folks there, but this is really bad. I told him the car ran bad from the get-go. Se said on Dyno Day that he really didn't remember my car because he did so many, but when I brought the car back in the shop that one of his techs said he remembered the car because it was pre-detonating. Lidio or I didn't hear it, but the tech said he thought it was apparent. Though he didn't hear it, Lidio thought it was pre-detonating from the way the dyno chart results were and mentioned it to me then. That is when I called LMS right away and they pretty much po-po'd it. I brought it back in anyway and they had it 2 weeks to work on the tune and said it was "fine". I got the car back and it ran so bad that I brought it back again and that's when they said the engine was bad.
So, many of you are thinking "523/434", really. Yes really. Lidio used HP tuning and has my stock file on a stick for me to take and tune anywhere else I want to go. The thing is now I can drive the car and it runs excellent. Backup camera magically works and the cruise is fine. Idling is at 700 instead of the 900-1100 from LMS.
So, there you have it. I made several mistakes but the car does run smooth and shifts about 7500 RPM.
Lidio asked me "are you going to go after LMS for this". I said I don't know. He said that it was apparent that they did not tune the car right and he guessed that they caused the piston failure. No one knows for absolute sure, but it's likely.

I’m sorry you went through all this, but I’m glad for you that you got your car back and you’re happy with the way it’s running. Enjoy the ride, even ONLY 523 hp is more than I have!
