E39A 2 or 3 bar?

Hi all, I'm very new to tuning and have been doing a lot of reading. I have only been as far as adjusting shift times an points in my wife's 6.2 Silverado.
My question is, I have a 2013 Malibu with a 2.0 turbo LTG and was wondering how do I know if it's a 2 or 3 bar map? I assume it's 2, but figured I should ask the guys that would know.

The E39 will read up to 255 kPa (36psi), or about 21.5psi actual. I would suspect GM would have fitted a 3 bar sensor.

Thank you, glad I checked. I'm looking at doing the VVE and don't want to use the wrong table.

Just keep in mind the VVE tables aren't 'real', all that happens is when you manipulate the values the calculations in the background take in to account the max map range. So if you changed the 2bar table, it is still going to change the VVE values in the same way the 3 bar would except that what happens beyond 200kPa isn't checked.
