remapped or just wonky software/gauge?

[Dave86]

Right I've got the 'torque' program on my phone and a Bluetooth obdii adapter that I've been playing about with, when i floor it its saying the boost pressure reads +1.2 bar which seems a bit high. I've also got an proper boost gauge albeit a cheap pfv one but this only shows +0.5 bar on full throttle however both gauges match perfectly from -0.8 bar up to +0.5 . So my question is what ones right i would of thought the obdii would be the most accurate but i don't know.
Got no record of a Remap and the car was completely standard when bought it.
Any advice would be appreciated
cheers
Dave

You'd need to get yours calibrated correctly to decide which one to rely on. I once got my calibration company to calibrate my Blitz turbo timer/boost gauge once. I was surprised how accurate it was 0.01bar difference at 1.0bar..
