I'm not a site sponsor, but yes, RedShift is working on my car.Hit up TeamValorRacing. He is selling his Comptech S/C but, AFAIK, it's mostly checking the belts and changing oil in normal intervals (3000 miles instead of the Honda recommended 5000-6500).
As 07CivicMD said though, how much WHP are you looking for? That would point you where you'd want to go, and take steps from there. Blue Rocket (a sponsor on this site) is getting his engine redone by Redshift after his AJP kit -- so you may want to check his thread out.
