TSB 11-07-07 Piston Failure
#21
There's nothing wrong with the 5.0. Everybody is getting all up in arms about nothing. The TSB is regarding aggressive aftermarket tunes causing a lean condition in #8. Ford has the right to be suspicious, especially with engine problems since all these #8 issues have been the result of aftermarket modifications. You can't modify your car, tweak it, and then expect Ford to come to your rescue when things break as a direct result. If you want Ford to cover anything that breaks within the warranty period....DON'T MOD.

You need to READ the TSB again. They are even saying an axle back exhaust is included in the list of known causes of #8 failures as well as clutch and oil pump failures. How in the world they draw a straight line between those is stupid crazy. How about the fact that they are having ( according to their own stupid flow chart ) the same failures with out any mods? Pdonket is exactly right when he said that you now walk into a dealership guilty unless proven otherwise. I also read it as Ford wants to force you to by only their performance add ons.

Mods dont void warranties. Modifications that cause damage mean they wont repair that damage. That makes sense.
The question here is it a manufacturing defect? afterall most people dont have a problem even with superchargers and nitrous. and people with nothing but a tune are having this issue pop up.
so what reason can you think of that several cars around 400whp have the #8 piston fail, but people pushing 600whp-700whp don't have the issue. it can clearly handle the power, tunes are made by the same people.
Oh, and the Tune for the auto helps so much.

Not saying that the tune is definitely not what's causing it, but just saying that it's not necessarily the tune that's the common denominator to look at.
Also those asking about a tune on the Auto, it's absolutely worth it. The shifts are so much firmer, the power feels much more on tap, everything is just sharper. While you might have a hard time chirping the tires on the stock tune with the Auto, on a custom tune it'll chirp through third if you want her to

It could be a combination of (3) factors:
1. Tunes push the car to the engine's tolerances.
2. People who use tunes tend to beat on their cars more then people who don't.
3. Far more people have tunes then blowers as already mentioned.
I suspect that Ford tunes their cars to allow for imperfections in engine build. Tuning the car leaves less room for error.

I think it very well be some things in the stock parameters that do not like being messed with on aftermarket tunes, being the engine cannot handle the parameter change.

For an engine to consistently blow one specific cylinder screams design flaw, no matter what the circumstances. If the tune was written poorly, I would expect lean conditions in all cylinders, or at least a whole bank. For one specific cylinder to experience a lean condition when all the others are fine says to me that something is not right, hardware-wise, in the engine. Specifically, it tells me that the knock sensor is not placed correctly.
For Ford to say that they won't fix your engine if you modify it is fine, that's how this game is played. However, for them to say they won't honor any part of the powertrain warranty if you install axle-backs or disconnect your battery is ****ing ludicrous. Like, I would expect mental fitness evaluations to be performed on the authors of this TSB, because I'm pretty sure they licked a little too much paint.
