Review on 🚗 ESUPPORT Car 2" 52mm Digital Turbo Boost Gauge Red LED Light Indicator PSI Meter by Gustavo Mathew

So delivery is ok however I read other reviews that the tachometer didn't work properly and was junk. I decided to take a chance because they may have faulty hardware or incorrect installation. I installed mine professionally and loved how digital it was. However, this is not accurate at all. I would be on the road and my RPMs would almost never 1100.1700.4500.3200 happen to stabilize at the set RPMs. Fluctuations of 100 rpm are acceptable, not 1000 to 2000 rpm. So I was advised to install a resistor on the signal line to filter out unwanted voltage spikes. Had this done and at first it seemed to work but the tachometer was still not accurate and was randomly trying to tell if my engine was running at high idle or low rpm. So don't be like me and take risks, just don't buy it, buy a more expensive quality option. Luckily Amazon gives me my money back so don't waste your money on the part I'm working on.
