Top Engine Cleaner... WTF?!

I went to the dealership today to get a "can" of it... and dude looked at me like I was lost in time. "Sir, we stopped selling that product years ago, what year is the vehicle? Oh, it isn't intended for injected cars..."

So I am standing there w/o a clue (no part number) and have to leave with my tail between my legs, after he shows me some "newer" products that may work the same... One was called "Cleen" and sounded like the trick.

So, now I have a few questions:

1) What is the GM P/N for Top Engine Cleaner?

2) Does this go in a full tank of gas, or am I supposed to pour it in through the up-pipe as described elsewhere?

Can someone describe the process to me? Will this screw up my cat and do I need to change the oil afterwards?
