I agree that LMS has developed a negative image for itself.
The Magnuson is a high quality supercharger. True, it can't do the BIG hp numbers some others can. Not everyone has limitless pockets though or even feels the need for 700+ hp. Many are probably happy with a fast, dependable street car that is fun to drive.

Yes, and this is exactly what I was looking for.

I'm still confused why a built motor was recommended for 580whp Magnuson car?

Seems to be overkill, not to mention over expense. I'd have put a stock short block in there, negotiated a discounted deal due to the circumstances surrounding the initial motor failure, and then walked away from the shop and taken the future care of my car to another shop.

I made a mistake. I could have purchased a long block from Levittown Ford delivered for $5700. But, since LMS gave a discount on the labor, I figured a forged short block was better. I clearly messed up. I went with their recommendation. I believe they gave me a discount, but clearly there was some profit in it for them. My salesman told me with the higher compression, smaller pulley and cai the car should make "more power", be more durable and rev higher. I also thought the car would be back much earlier so I could do car stuff this summer. A very time consuming and expensive learning process. Also, during this I lost both of my parents so my focus was not on the car as much as it should have been.

My condolences on your loss, the hobby should be a stress reliever not cause more stress than needed. I'm with you on the simple setup and fast and dependable street car. With a new tune, it seems like other people are having that with the Maggie's so hopefully it works out for you soon and you get it squared away so you can enjoy the good weather before winter hits. Any updates with the new tune? Are you switching up tuning devices now as well?

The new tuner emailed me yesterday stating that with the help of a guy at Ford they wiped the CPU. I emailed that I was concerned that the engine might have been damaged from running lean. He emailed me last night back stating that the new motor sounds very good and healthy and that I shouldn't worry about it at all. Good news. He will hopefully be tuning it early next week. But, their shop is very busy and he told me this when I brought the car there. I am pleasantly surprised that he has gotten the CPU wiped. Now, just tuning. I will put up results when I get them. Also, I'm heading back to the Detroit metro area next week and the car might be done by then.

my condolences on the loss of your parents. that has to be stressful enough by itself without adding the car issues, glad to hear the new shop is making progress. hopefully once the car runs as it should you'll be able to put this nightmare behind you.

The only thing that confuses me is, doesn't most engine damage happen at WOT under load? And in most tunes I would assume that the tune commands .78 lambda and max timing around 18 degrees. Then the widebands correct fueling to keep it at .78 I can understand driveability issues, but wot should be pretty simple.

Livershat tune at wot hits 20 at 6800 to 7300 but is about 16-20 depending on rpm for timing. Livershat tune issue is not wot. It’s drivabilty and going into boost they have no clue what they doing on they own package it’s sad

Exactly right. WOT is not the issue. It's trying to drive a bit briskly that is horrible: Shifting, throttle response, flat spots and now seriously lean conditions. They do the WOT on the dyno but that's not real life driving.

$4400-4600 long block. PM if/when you need one.
Consider Beefcake special w Lund or Whipple w Flare or PBD next time you go FI.
Sweet spot on these cars for performance per dollar is stay 700-800 wheel max on a proven solution and just budget for a $4500 long block and $2500 labor and supplies just in case.
Above 800 for extended periods of time requires a very dialed in $etup and tune. It is also very difficult to hook it all up consistently in most street situations.

If you kill a second motor running a crap tune you are an idiot. Everyone has told you to get another tune immediately before you ruin that motor so do it now. Email, call, pay and get on the schedule. Baby that car till you get it tuned properly.

LMS put in colder plugs when they originally did the Magnuson in March. After the new engine was installed they installed another set of plugs. The tuner emailed me Saturday stating that the engine runs strong he thinks it is fine. Should be doing the new tune within a couple of days. When I get back to the metro Detroit area I will likely be done and I can report back.

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.
