The word "boosing" is often used to describe the act of increasing or improving something, but there are many synonyms that can be used in its place. To enhance something, you can instead use words like amplify, augment, elevate, enhance, expand, or uplift. You can also use words like boost, heighten, intensify, strengthen, fortify, or reinforce. Words like improve, optimize, refine, polish, or perfect can also be used to convey the idea of making something better. Depending on the context, these synonyms can be more appropriate and can help to convey the intended meaning more precisely.
