I'm getting a boost gauge and i wanna know which one will get a more accurate reading. And which gauges(brands) are among the most accurate

 

I'm not an expert in the inner workings of a boost gauge, but...

Electronic is "supposed" to be more accurate, but it still makes me wonder how much more accurate it is. The air still has to go through a sensor which causes the needle to move. Electronic has an external sensor that sends signal to the boost itself, while the mechanical is built in. One can argue that essentially, an electronic boost gauge still uses a "mechanical" sensor, just that its outside.

search!

 

electrical is better...mechanical tends to read high or low after its been used for a while

 

the closer the boost sensor is to the source of pressure/vacuum, the quicker it will respond. Since the electrical gauges have the sensor mounted under hood (within inches of the manifold if you choose to mount it that close), they should have better response compared to the mechanical gauge, that you'll have to run a vacuum line all the way into the cabin and into the back of the gauge.

Mechanical gauges also have a lot of needle pulsation compared to electronic gauges, making them harder to read.

 

Defi...quality product that doesnt need replaced

 

Got mechanical, needle moves around to much. Like the smoothness and accuracy the electical gives. More pricey, but worth it.
