my car is boosting at 1.5 bar. Any idea if a td04 will help it? diesel - low rev high power. Full boost comes at 2k onwards.

However - my turbo is too small i feel to do so much of work. After remapped i got approx 170 ish whp and 380Nm of torque...when i reach full boost - it starts to whine ...like a mechanical sound which is annoying everytime i reach full boost
