Add-On Gauges

Know your Air/Fuel Ratio – all the time..

Gauges are optional, though highly recommended, particularly for forced induction applications where it’s a good idea to keep an eye on your air/fuel ratio even after tuning is complete. It’s a nice ‘safety’ to let you know if anything has changed with your setup that you need to address (clogged injector, etc) that could help you prevent a meltdown!
