Should smoke come out of my exhaust when I use Sea Foam Spray? [SOLVED]

I used a full can of the Sea Foam Spray through the throttle body. I followed every direction other than I let it hot soak for 20 minutes instead of the 10 minutes. I got little smoke out of the exhaust while spraying the can into the throttle body, but never saw any smoke out of the exhaust afterwards. I was wondering if that was a bad thing, because I was expecting lots of smoke? Thank you.
