93 4runner figured out performance issue

My 93 4runner with a 3.0 has a reman engine with 17,000 miles.Since I bought it it has been sluggish,has hesitation when accelerating,and just a dam pig.Not throwing any codes.
I read the write up about moving the knock sensor to the engine lift hook.
So I bought a pig tail,drilled the hook,and tapped it to a 12 mm 1.25 pitch,and installed a new knock sensor.
Performace issued solved.Truck runs like a top, and has so much get up and go.

Does this now bypass the knock sensor by moving it to a location where it wont sense anything?

Not sure, I did not want to pull the top of the engine down right now.

I don't know if this would affect your oil pressure gauge but did this improve the reading as well? Does it pass smog?
