standard map sensor max boost?
I have a problem with my boost gauge reading 2 bar, I know this is far too much as the car was mapped for 1.65 bar.
I dont know if the gauge is over reading, I used the boost gauge on Torque app, which I beleive takes the reading from the map sensor.
However it only shows 1.5 bar max boost?
Is this the maximum boost the standard map sensor can see? And if it is how is it possible to map a car for more boost?
Car is a widetrack blob sti running 409bhp with supporting mods.

Thanks 53, seems neither the gauge nor Torque app are accurate, or one of them is accurate but need to find out which one
Either way if its over boosting or under boosting I still have a problem.
Cleaned the bcs recently with brake cleaner, replaced a split pipe at the turbo t peice, checked for anymore leaks with a smoke machine at a garage.
Could I have ruined the bcs with the brake cleaner?

However if the map sensor can see 1.7 bar it causes further confusion as torque is only seeing 1.5 bar.

the ecu will only show a max of 1.55bar... effectively 255 being its highest possibly number for the size in memory it is allocated.. the sensor normally maxes around 1.65bar, occasionally 1.7bar but usually find 1.65bar so I suspect it has been mapped with no boost cut if it overboosts.
double check for leaks in pipework to actuator and boost solenoid

Many thanks JGM, I will check the pipes again, I was wondering if I find all the pipes intact, and the new gauge still reads over 1.65 bar, could you suggest if there is anything else that might cause this issue?
Thanks

Checked all the pipes again, still cant find any splits, I would like to replace the hoses anyway, just in case I have missed something, do Samco make replacement hoses, cant seem to find any?
