Strange boost issue w/HX40w 18 cm2, normally starts to spool at 1.1k I have boost set to 30 psi (gauge) on a hot day it will boost a little less and on a cool day it would spike a little higher upon initial throttle to WOT there would be a very noticeable cloud of black smoke which would clear...
I see a few here had installed quick spool valve on their 6.5td however at least one had stopped using it.
Aside the quick boost feature is the back pressure off boost that causing issues at cruising speeds, or?
While looking at BOOST sensors a question came to me, it appears when using a 2 BAR sensor and running a higher pressure ratio than 2 BAR it seems there would be a de-fueling issue, or am I thinking too far into it?
