first of all, i dunno wat makes ordinary guy so sure that mit storm is the lousiest turbo diesel vehicle, he sounded like he tried all turbo-diesel car like ranger, fighter, rodeo, trooper, sorento, kyron, discovery, freelander, frontier, land cruiser, hilux, prado and so on so forth... every car got their pro & cons, dun just simple gave this kind of comment...
As for performance part, i m using pajero 2.8 diesel turbo, i didnt do much for the performance part... only a volts stabilizer to enhance the electrical part, but my fren invest in air induction, exhaust, and a computer and the performance kinda good... overseas user replace the turbine and make high boost too...
