Its not the pro version & I dont believe the D-Jetro version comes out for WRX
Boost control is set toi allow up to 1.4 bar. I can only go to 1.1 ish before it feels like boost cut.
So I have read
HERE the earlier models only go up to 1.2 bar, which could explain why I am hitting this boost cut. I am hoping the MAP sensor is being maxed out & then cutting the fuel as it would if it reached its setpoint (when set to under 1.15 - 1.2 bar) as a boost cut.
The 99 model MAP sensors can read about 0.4 bar higher "apparently"
Is this making any sense, or am I heading a totally wrong direction? & something else is to blame?
