Who can tune this thing right?!

I'm not interested in arguing about it . I've done it . What I've said is not theoretical. With a hx60w most of what you've written is simply not true . They don't spool slow without over fuelling to achieve it , they actually spool just as quick if not quicker than the vgt and you don't close the shi#t out of it creating a heap of back pressure to do it . As far as running down the road, if you were to log it , they behave nearly identical to a vgt . Again I have done it , each to there own . The Borg warner crap fitted without a waste gate is a mistake but a hx60w as used by cummins is a very viable option for those that want something other than a vgt.
