Thanks for the feedback.-no dip in boost
-more linear torque
-egt the same as 3 needles +tillx
But!:if I drive uphill in 4 gear at 1500 rpm (sotto coppia)egt are higher about 50 degrees cause boost is at 5/7 psi instead 10/12psi .
Gauges changed my way to drive...
Try closing needle #2 a little (small increments/notch at a time). Check spool needle#3 (lever touch vane limit stop)_should be OK for small adjustment now.
