Review on 🏎️ MOTOR METER RACING White Amber 30 PSI Boost/Vacuum Gauge Kit - Waterproof, Pin-Style Install with Electronic Pressure Sensor by Dee Rawls

It all started with the needle not reading zero when I plugged it in. Read about 2-4 psi with the engine off. It really didn't work from the start. Raising the engine to 3000 rpm only raised the pressure to 10psi when the mechanical gauge (now broken) was raised to 24psi. It stayed that way for a while and now reads full scale (30psi) with the engine off. Because I had problems with my first order, I received the mechanical version instead of this electronic version. I will not bother to return this faulty product. Consider it a loss and get the best branded boost sensor.
