Knock sensor problems and lacking performance lt1
So while showing my car off to my cousins, you know riding it real hard, I noticed that it had good power from a stand still or roll but was taking what I feel was around 8 seconds to hit 60. And thats slow for a stock lt1 which mine is not. Around this time my check engine light came on. I drove cautiously the rest of the way home checked the code and found it is the 43 knock sensor code. After checking the sensor and wiring I replaced the knock sensor. The wiring had 4.9v whith key on. The old sensor read 3.2 mega ohms. After replacing the sensor it seemed to perform better but still not as good as I hoped it would (keep in mind im pretty sure it hasnt ran like it should since i got it so its hard to establish a baseline performance). Then the other day the code pops back up. Im not sure whats wrong. Any suggestions would be great since a ticket limits me from taking it to a shop.

Did you torque the new sensor to spec or just throw it in and go until tight? Those knock sensors are sensitive to being overtight, and if you overtighten it, it should be replaced again.
