2000 7.3L PSD CC XLT

The guys at vavoline gave me a bottle of thier fuel injector cleaner, the bottle says it treats up to 60 gallons, used entire bottle. The truck seems to have more power. It could be my imagination though. Do any of you guys recommend using this stuff ?? Has anyone had good luck with it ??
I also use power service in the winter and have been using that once a month
in warm weather.. Does power service clean my injectors like they claim on the bottle ?? The valvoline cleaner says use one bottle every oil change..
Thanks for any info on this ..
