Most people replace the Crank pulley and Alternator pulley. The majority of where the weight is really
if there is a noticeable difference
Difference in how quickly it revs up to 6000 rpm's - Yes
Hp difference - NO
I have the MRZ Lightweight Version Pulley.
and if a tune is required
Short Answer NO
Pulleys don't require tuning
thanks guys

I'm going to cut you a break just this time 
https://www.cobaltss.net/forums/show...erdrive+pulley
I paid $174 + Shipping for my MRZ and install was only 40 min. labour
Keep your receipt to prove it was installed professionally so GM doesn't hassle you
