thoughts on crappy boost gauges

[i3igpete]

I know we had a discussion on 3si about slow boost gauges. Originally the problem gauges were prosport, and I recall that the guy from prosport actually made an account to tell me that the needle response on their gauges were fine. well, i have reason to believe that the stri gauges use the same stepper motor as the prosport, since my boost gauge response was about as slow as the one pictured here.




What's interesting to note is that although the sensor is applied the overboost pressure, the warning light doesn't come on immediately... it waits until the needle reaches the warning zone, rather than turning on right away. lazy circuitry if you ask me.






needle speed of the prosport gauges:


compare that to the needle speed of defi gauges:
