I have been doing some research on some performance upgrades to my '00 LS Sport V8. What are your thoughts on swirl control valves? Places like http://www.spiralmax.com/ tout them heavily (of course they are trying to seel them too). So I would be curious to get some feedback from those of you who are far more educated on performance mods for our LS darlings than I. I appreciate your help!
