PowerCard Upgrade Kits
Now you can have the latest in digital tuning technology for your supercharged MX5-. If you haven't upgraded your JR Supercharged MX-5 to PowerCard fuel management you don't know what you're missing.

Fuel delivery is precisely managed to deliver seamless drivability in boost, out of a boost and everywhere in-between. Systems tuned by PowerCard have more power across the whole RPM range because the Air/Fuel ratios are optimised. And top end power can increase as much as 10hp.
