Can you just put a bigger fuel system on it to make smoke more?

Adding a bigger fuel system alone will not necessarily make more smoke. While increasing fuel flow can contribute to smoke production, other factors such as engine tuning, turbocharger setup, and exhaust system modifications play significant roles in smoke generation. Simply adding more fuel without proper tuning and modifications may result in inefficient combustion, reduced engine performance, and excessive fuel consumption, without achieving the desired smoke effect.
