from what i hear it doesn't work. if it did then everybody would have one.
that goes along with a big list of things that don't work.
1. ecu upgrade like jet and others.
2. ebay chips that supposedly give you 20 hp.
3. tornado fuel savers
4. ram air extension to your Intake
5. electric superchargers
if you want to go with an ecu upgrade then you might want to go with the greddy emanage or safc. correct me if im wrong.
