i had a z6 with a zex street cam and skunk 2 gear. dont know if the street cam is stage 2 or not, bell yeah i could definately feel more pull throughout the whole powerband. it gave my car a better launch[more torque] and when vtec hit i could feel my car jolt forward more. this was in a 92 si.
the only thing i didnt like was the cam i had was kinda loud, but i think all cams are loud. the idle was fine.
