What would be some easy performance mods to a 98 pontiac grand prix gtp ?

I am wanting to do some easy mods to my gtp but dont no where to start. I was just wondering if there was something simple like a adjustment under the hood or doing something to the waste gate. Can someone tell me where to start? Also I was told that you couldn't put a cold air intake on a gtp because it is supercharged is that true? Or will a cold air intake for a regular grand prix work?

I had this exact car back in 98-99. The easiest, simplest most reliable thing you can do is to get a different pulley for your supercharger. A bigger sized pulley will make the charger turn faster. This will put more air into your intake manifold and give you more power.
Back then I found these pulleys on the internet very easily. I dont know if theyre still out there, but I bet you can find one.

BTW. i never did the mod. I ended up just selling the car and buying a vette. good luck
