probably a dumb question, but I am gunna ask anyway

how accurate is the PFC at reading speed, boost, water temp etc?

I know is shouldn't (and doesn't in my case) replace manual gauges, but is it accurate?

 

I've heard that the temp can be up to 10 C off, someone correct me if I'm wrong though. I still use mine as a guage though, its still a HELL of a lot better than the stock temp guage. It also has tons of different things you can monitor all at once.

Back in the day, somebody on the big list worked out that the PFC read boost a smidge low...I believe it converted out to .7 PSI.

 

Ive heard that they are not too acurate

 

As accurate as your car sensors. I trust mine For everything but boost. You should ask this in the PFC Forum. The gent's there may be of more assistance.
