id say you would get away with this at 32 or 33 psi, but anymore than that and you would have to fit a 5 bar sensor as the fuelling difference would be to great
Of course the problem with the 5 bar map is that you have reduced the resolution of your map everywhere else. Effectively, if you fit a 5 bar, you only get the same sized table to map the car. This means that more interpolation is required between points, which is why most choose to use a 3 bar!
