Tweak

The term “tweak” meanings:

1. To adjust a screw or component by making a very slight adjustment: This is the more common usage in automotive and mechanical contexts. It involves making minor adjustments to achieve optimal performance, alignment, or operation without significantly altering the component.
2. To bend a component to such an extent that it will need to be replaced: In some cases, particularly in colloquial or informal usage, “tweak” can also refer to bending or deforming a component accidentally or intentionally beyond its elastic limit. This can render the component unusable or require replacement.

In professional automotive and mechanical settings, “tweak” is often used in the first sense to describe fine adjustments to achieve desired specifications or performance characteristics.
