As of right now the only thing done to his car has a stage 2 or 3 supercharger with the boost turned up. The things he has for it:
PCM upgrade
Headers
3 inch stainless exhaust
3.4 pulley
New supercharger snout
2 inch lowering springs

I think that's everything but im not sure.

I know what you meant, I don't know what a stage 2 supercharger is. How is it different than a normal supercharger?

It may be a ported one from one of the 3800 vendors.

Stage I is having the outlet (underside) ported to get more flow into the engine.  Stage II is having the inlet ported (usually to 78MM) and removing the air divider.

If you "goggle" Eaton M90 porting there are several articles on this.

I did a stage I myself, IMHO a good free mod.  I have a GEN V to put on but that will wait 2 more years.

I dont know why people waste their money on nose cones for the EATON blowers, unless you are milling it down there really isnt much room for improvement.

My dad bought a new one because it comes with a 3.4 pulley already on it and has a quick connect design that allows you to quickly change the pulley to a smaller size. Thats what he told me but i may have misunderstood him?

Well last night my family went out to dinner. Me and my dad took our cars and on the way back we raced again. From the roll starting at about 25-30 i took him by a car length. I held a pretty solid 1 car length the whole race then we let out coming up to an intersection. I was going about 85 when i let out.
