Since I think RacerZX is the only one here who has had the Stillen Supercharger a while, this is mostly directed towards him (thought others may be interested instead of just a PM)...
What are your feelings to date, (ie, several years, many miles)?
Do you recommend Stillen as the installer?
Would you do it again?
Any concerns with warranty?
...I ask because I think their price is very fair, and I am considering it.
