Will this help my car the way it was before I poured this additive?

So recently I had my 2003
Honda Element re tuned/serviced for a synthetic oil change, 3 stage injection cleaning service along with a set of new spark plugs. Right after that device was done, my truck ran like a brand new car and felt very peppy as it had no problem getting up to speed and climbing up steep grades. However, I myself decided to pour a Lucas fuel injectior cleaning additive and I noticed that my truck doesn't have the power and performance that it used to have before I poured this additive. This has been over 2 weeks ago since I've added this thing and I have another problem with my engine making a humming sound as I accelerate or cruise on the highway.

Should i get get this service done again(the whole process) so I can have this additive flushed out? Maybe that should help.

Did you pour in the cleaner on a half tank? Top off the tank to dilute it and try again a few tanks later, this time with the recommended amount of fuel.

I don't think the Lucas is to blame. You don't say how long since the original cleaning. If it is clean is no sense cleaning it. Unless there's some contamination in your gas tank. Did they clean the entire fuel system including the tank?
