I was wondering how accurate the stcok digital "Bar Gauge" really is versus an aftermarket boost gauge? I am installing an aftermarket gauge this week, but I just wanted to see what everyone else who has aftermarket boost gauges think about the accuracy of the stock Porsche disgital gauge?

 

The aftermarket boost guage will be very accurate because its deriving the info straight form the source... tahst what I have.

 

Mark - Did you notice any difference in boost reading between the stock digital one and your aftermarket one?

 

I use it.. cause its instant... and I use a analog guage..... I need to know if tit really 1.3 or 1.4 bars... and it seems that the BAR one is lazy...SLOW.

 

the stock one *really* sucks. it's not accurate at all.

my car was reading 1.2 bar when, in fact, i was boosting up to 1.5 bar! and then, for some reason, at redline, stock gauge would always plop up to 1.3-1.4 bar but the car's only boosting 1.2 @ redline.

get a real boost gauage - stock one sucks.

compare readings when on a dyno you'll know how accurate the indash unit really is.

 

Where are you going to install the guage?
