Anybody Familiar with Ford "Fly-by-Wire" Throttle Assemblies?

Cats do melt BTW. I've seen it many times. The ceramic material usually breaks apart and plugs up, but the ceramic material can occasionally melt if there is exessive heat. Sometimes from a lean condition or driving with an ignition misfire that is dumping raw fuel. That is why a Check engine light will flash under a misfire, it is a universal warning of imminent catalyst failure (meltdown). Google it!

and we all know the internet is never wrong

now really it is blockage by carbon build up and causes increased heat and starts on fire once on fire will melt the metal casing

unless he was hitting or smashing the cat with something then your idea is right with it breaking apart but the ceramic doesn't melt it burns

Ok

Why'd you edit your post? And if you'd mentioned you were a mechanic in the first place you'd have more credibility.

These cars throw codes for everything, you should know that. If it was running lean, or had a blocked cat, it would code, probably for 02 sensor or something. Thanks for throwing your ideas out there, but dude, calm down.

Don't know why its doing what it is, but we're gonna get it back on the dyno and see. Also gonna swap the "cali" intake for a less restrictive one and retune for better breathing.

Continuing to troubleshoot, I think it may be belt slip. Never thought about it, but since removing the load from the alt (took out the AB750.1), it hasn't felt the same. Wish I would have thought of it when the amp was still in, so I could check for sure, full volume vs. subs turned down.

Still not certain this was the problem, but something to consider. A 270XP could kill HP 6-8%, and thats not accounting for slippage.

I thought better of arguing with people on an internet forum. I learned that a long time ago, I just got sucked into it momentarily!

Hit the dyno...hit the dyno...hit the dyno......until its data logged and the duty cycle percentage on the throttle body is checked you are just grabbing at a gnats ball hairs..meaning you might find something but you wont know it if you will cuz ya cant see it or feel it lol.
