Review on 📊 Accurate and Reliable: Auto Meter 5705 Phantom Mechanical Boost Gauge, 2.3125 in. by Tutcht Cobb

Bought a boost sensor to troubleshoot a diesel engine. You just need to know if the boost pressure before the intercooler is close to the boost pressure after it. When I unpacked it, the meter read seven psi with no connection. That's not much for a 60-pound caliber. Sent a few emails to the manufacturer asking if the needle position can be changed or how to fix the sensor. No Answer. Since it works for what I wanted, I'll use it instead of messing around with a return for another. I would not buy another from the same manufacturer as the quality control is obviously poor and customer response seems to fall into the same category.
