I'll try anything.. Tune issues.

Alright alright- before everyone goes up the ladder on my previous post-- allow me to remove my foot from my forum mouth. It would appear I have a TB issue afterall. Now- maybe I can get some guidance with regard to the TB. It's a BBK 62mm that's been on for about 8-10 months.
I come across a gold-ish colored piece of machined metal that appears to match the color of the idle control. This piece is about a half inch long and cylindrical- almost looking like a piston of sorts. It was found sitting nicely on top of my radiator cover. Any thoughts on a fix, cause, etc?

Could you take a picture of both the piece you found and the BBK TB? This may help us identify the piece. At the very minimum, I BBK will be able to see what's missing or broken.
Either way, I'm sure we'll be able to get this figured out!

Lots of custom tune issues here lately, or so it seems. Mostly on the 4.6's. Seems like no one is exempt. Bama, Brenspeed, Steeda.
Best Regards,

This is a pic (rotated) of the right top corner of the TB and idle control (gold). You can see the idle control is hollow in this pic..
After I re-inserted the found piece, it looked normal-- in this pic..
On the left of the below pic is the piece I found on my radiator cover. After I re-inserted it into the idle control and then removed it, it pulled out (with it) the silver piece on the right. Maybe this is the issue????
Those two pieces fit together as such..
at this point, both small parts are out of the car.. I disconnected the CAI and found the TB (with engine off) spring loaded closed, which I expected. When I pushed it open, it returned to closed. I checked all electrical connections and everything looks good.. Is this the point at which I dis-assemble the (right) side of the TB and find out what the hell is up with these two random idle control pieces?? Anybody seen this?

i believe that is the plunger to adjust the tps voltage, probably could take the motor side off and re-insert. adjust to stock voltage..
check out below video..

So here are the three parts all out of the TB.. allen bolt to allow the idle control (gold) to be backed out.
I talked to BBK and they said the three parts are pressure mounted together upon construction of the TB itself. I'm hoping they'll let me just send these three back instead of having to uninstall the entire TB. We'll see... MTF

Luckily mine is still running strong. Steeda still has my vote. Was not trying to flame any of the tuners. Without ya'll, life would suck. May be that we are just seeing the influx of more and more people running tunes. Looks like this thread was totally not tune related. Also plus 1 on what Nuke said. An aftermarket TB N/A is just asking for a problem IMHO.

Get your money back and put it towards another mod.

Alright- so I emailed BBK. The response I got from them is that the TB is very sensitive to voltage changes and the new tune likely changed something. Either way, the result was that I blew the idle control open at some point. I have subsequently re-installed the OE TB and retuned.
Coincidentally, while removing the BBK TB, I look down and see the spring for the idle control sitting atop the pan below the radiator-- so it came apart while under power and I eventually found all the parts-- what are the chances!?
As much as I hear about aftermarket TBs causing problems, do they not provide ANY performance gain?
