Can apps like Torque, connected to an ODB unit, accurately measure boost?

I see the app has a gauge for it but was wondering how accurate it is reading from the ecu.

yes it can measure boost. as for how accurate you never know, i have used it and to be fair it wasnt far out compared to dyno run.   but i wouldnt rely on it

my app was measuring higher than the actual boost was giving... but you know that, you read the build thread

I forget stuff dude... a lot of stuff, especially details.
