Default I must have more Boost

Some people think more boost just = more power.Without thinking about Drive pressure higher EGT's turbocharger over-speed.
The boost should only be increased to match the fuel curve for smoke and EGT control.
I changed turbocharger before I had --# of Boost now I only have -# so I will just close off the wastegate. now you have ---# of hot air

I follow you.

Remember, Boost it a measure of restriction, not flow.

Actually the way I read the thread was that you probably got pissed from some smarty that was in his own little world about diesel theology.
