3 bar are you serious, i don't think you can even flow more air through the head than 1.5bar.
On another note a TD06 will be more or less unusable on a 1.5 5efte, let alone the 1.3 4efte, you will literally have about 500rpm of usable boost power, i.e revving to near the limiter to get on boost, then when you change gear you will be back off boost and no power.
If you want big power avoid TD05/06 they are laggy as hell, take a look at the vf series or hybrid td04 etc.
