how accurate is the stock MR boost guage? or any of the guages for that matter?

 

Accuracy is not consistent across every gauge. All I can say is that my stock boost gauge was accurate in the beginning and still was the last time I checked, but I run so much more boost than it can read that I can't really tell anymore.

The voltage accuracy isn't a big deal. I mean, mine always sits where it should and fluctuates according to changes. The key is noticing if it's a lot lower (or higher) than normal at a given point in time.

I use my oil temp gauge all the time, and I don't care as much about the accuracy as I do the fluctuations when racing. For a given set of conditions, I know what to expect and when to give it a nice cooldown.

 

cool...thanx

 

accurate up to 21.7557 psi

 

Where did you get that information?

 

1.5 bar = 21.7557psi...
