i guess the cheap way of telling would be a boost guage, but bearing in mind i think the other 2 are sleightly leighter in weight than our a3s they may just have the edge.
my agu a3 150hp has just been mapped to 194 and the boost peaks at 19psi, and you can deff tell its mapped, i did beat a gti on a privet meeting and also a focus st quite easy.
