Please excuse a silly question but when our turbos only run at say 2.2 bar why do we need 4 bar and where on the car do you see 3.5 bar?
Any why would Ian blow a 3 bar?

The ecu needs to have the lowest pressure scaled against the voltage range.
E.g. 0.5v - 4.5v sensor range to the lowest pressure 30kpa or 0.30bar.
Remember your engine will run at vacuum. Vacuum is just low pressure. Lower than atmospheric.
Either over pressure on the sensor range (running more than 2bar gauge pressure) or shit sensors.

3 bar map sensor covers you for 1 bar vacuum pressure and 2 bar positive

Sensor could be failing due to the way they are mounted I.e too much heat or vibration

I run a 5 bar sensor on mine (still level 8 management), was then live mapped on the road

Heard them bhp sensors are rubbish too so I’d get a decent genuine one buddy

There should be little reason almsot any sensor could not be used, but yes the ecu will need re-tuned to suit the voltage/pressure scalings of that sensor.
Problem is most cheap sensors these days are Chinese.
