1995 4.6 Mods

Having been away from high-performance for so many years, I am a bit lost when it comes to the later computer-controlled, fuel injected engines. So, what can I do, easily , to get more out of my '95 Grand Marquis? I don't want to get into heavy mods, but I'd like to see 30 or 40 more horsepower if it can be done.

Thanks!
