thanks, guys. Please bear with me. I am still a noob.

So if I currently have a 2.9" pulley with 18* WOT timing and 0 KR you guys are saying its perfectly safe to drop down pulleys regardless of what my boost # is as long as I can make ~16* timing at WOT with 0 kr? even if my boost shows 16PSI this is perfectly safe? As long as I show 0 KR?
