You are quite welcome.
(I literally just now saw your posting, BTW).

I hope it helped you.
Mine is holding up very nicely more than two years and thousands of miles later.
I happened to look into the throat of the throttle body a month or so ago while doing something else to the car (hey, why not?).
There are no new scratches on the polished bore, so there is no binding like what used to be happening.
And no hesitation or "snap-on" behavior like there was before.
There is absolutely no question in my mind that the new throttle body fixed the problem.

Whether polishing the bore had any performance effect is certainly debatable, but it looks nice.

Oh, and the throttle plate and bore are still squeaky clean.
No oily film, no dirt, nothing.
