I own a 2002 ls1 z28 m6 and im looking for more power

I've been reading up on the pros and cons of both a supercharger and a turbo. I used to have a twin turbo import before i came over to the domestic side of the family so i kinda know what its like. but ive never ridden in a supercharged car before or driven in a supercharged or turbo'd ls1. ive been looking at centrifugal and twin screw superchargers and the STS remote turbo system. If anyone has a supercharged or sts turbo'd Ls1 in North Jersey reply here or send me pm, id like to go for a ride to see what its like so i can make a further decision.
Thanks
