Catastrophic engine failure question.

Hi guys,
I need some help/ opinions on what could caused this. I will provide as much info that I can at this time with what the person has told me.I meet up with him on the weekends as his son plays hockey on my sons team if any of you need more info.

Its a 04 GT, has 61000 kms on it, original motor, all stock except magnaflow from the stock manis with catts which are about a year old.. He decided to go with Bama and also ordered a bbk tb, not sure which one as I see there are three on AM, and a spacer. He installed the tune on the 8th of Oct I believe and that night took it out for a spin. He said the car ran great, pulled and ran well. The following day he took it out of the garage and around the block then parked it to install the tb. When the tb was installed he started his car and said it idled really bad. He let it idle a little bit and said he smelt something burning so he shut it off. He looked under his car and one of his pipes just after the Catt was red, no cel or any other codes. After an hour or so started it again and instantly the motor was knocking. Shut it off right away and removed the spark plugs and said number 3 plug was melted. He is convinced its the tune but I'm not so sure that's the culprit. Could a bad tune kill an engine at idle that quickly with absolutely no cel or any other codes??

Again this is what he has told me and I'll ask for more info if some of you require it. He has contacted Bama but what I have read from the email that it looks like he is pretty much on his own.

Thanks in advance for any help or possibilities on the issue.

His best would be to put his car back to stock tune, stock TB and basically just the way it was before he installed his new mods. Replace plug #3 and see how his car runs. If it's still showing similar symptoms, I'd say he did his modding at a 'wrong' time.

And if not, the tune is going to be the culprit here. I can't imagine tb and a spacer melting shiet up on his car. Bama has history of sending 'incompatible' tunes, I wouldn't be surprised if he's running a tune made specifically for an entirely different car with different mods.

Happened to me once, my car wouldnt even start/do anything each time I turned the key, and it was showing ABS codes. Returned it back to stock, and it ran without any issues.

Spoke to him this morning, apparently he has some kind of snake camera and can see damage on the piston. Can a tune really break an engine that quickly at idle?

A bad tune can exacerbate an existing problem.

It sounds like an extremely lean condition. The only other thing would be lack of oil, but that would affect more than one cylinder.

Keep in mind all of the parameters changed in a tune. If one or more are way too high/low, it can certainly cause damage. A TB and spacer are not going to fry a spark plug.

That makes sense. Are you sure he properly secured the TB? One question is why it only affected the one cylinder? Or did he only check one?

He told me that he removed all the plugs and only found the one.
