That's exactly what it feels like! I hear ZERO turbo whine/whistle and never a surge of power.... I suppose there is a link here for me to start this...I have only had 1985 and older diesels so this thing looks like modern science to me... Oh by the way I work for a company that supplies parts to Borg Warner Turbo Systems and Detroit Diesel Reman...I should know a little bit.....But not on this baby
