high torque, low rpm, turbo

I'm not sure if this is a limitation of the game or myself, but I'm trying to recreate my 2007 Volkswagen Golf V GTI engine, and the hardest part is getting the torque band to be represented properly.
I've looked up several figures, which I could list, but I think its more important for me to understand the general strategies in getting low end torque appearing on turbocharged motors - and possibly accepting that this isn't something of high priority to the game, and if I can get the horsepower/torque figures correct at all, thats great (especailly using real world numbers).
For interest, the figures are listed below, the key one to note is maximum torque from 1800-5100rpm (280NM), I can get as many as 400NM, but all occuring from 2700rpm+ :/

EDIT: 17.6 PSI appears to be 1.2 bar
