Review on 📊 Hewitt Industries Combo Pyrometer & 50PSI Boost Gauge Kit with TruckMeter by Douglas Irwin

easy installation. One of my fittings was bad (turbo gauge) but Louis at Hewitt sent me a replacement very quickly. Turbo boost pressure is not accurate and cannot be calibrated to zero. The temperature sensor works fine. Both need to be drilled into the engine. So if this is beyond your skills, pay to install it. It's not hard, but getting to the intake manifold (boost) and exhaust manifold (temp) on some cars is the tricky part. Update ** - pyrometer died. No warnings or intermittent crashes. One day it worked, the next day nothing. All cabling is retained. The pyro tubes were not burned on the manifold or other engine components. There is no logical reason for the rejection - except that he is dead. The turbo sensor still works, but the lack of calibration is annoying. I don't expect extreme precision, but at least back to zero (or a simple arrow-zero function). Update: After speaking to Hewitt Industries, I was able to determine that the pyro sensor/wiring was within spec.
