Boost reading.. PSi3 or Gauge ?
Which will be more accurate ?
PSi 3 reads max boost as 1.12bar
Digital Boost Gauge running off a vac hose thinks max boost is 1.28bar
Car is a PPP'd STi v7
Cheers !

I have differences, PSi3 vs SPA Gauge. The sample rate can be changed on the SPA gauge which I did and the readings are now closer IIRC. Previously my SPA gauge was seeing 1.7bar and the PSi3 1.55 bar (PSi3 only reads upto 1.55bar) and it turned out the SPA gauge was picking up all the boost spikes and I needed to change the sample rate which then helped things.
