Any advice on how to boost my Hp from the stock 435 to at least 500hp on my 2017 mustang GT?

Sure, bolt ons like a cold air intake, full exhaust (new headers and mid pipe, removing resonators/catalytic converters) and a custom tune should help. If you want you can also try a free-er flowing intake manifold (CAI bolts to a throttle body which is connected to this). You may lose some lower end torque but it will show more gains on the top end.
