Innovate psb-1

Easy to install and program. Good readout. Good instructions. Everything you need is in the box !! Thanks !!

Florin Voicu
Excellent gauge!

Highly recommended. The boost safety cut out solenoid included is a life saver for your motor! It cuts boost if you are running too lean or detonation is sensed.

Jonathan De Jesus
Great gauge!

Bought this gauge as I wanted to equip an oil pressure gauge but only have 2 gauges in the car. Bought this for wideband and boost and it works awesome! Can change display if boost or wideband is your primary one you want to see. Would recommend to people looking to clean up your gauge setup.
