hey guys

i just installed a 1.2 bar actuator in my evo 1. one of my friends gave it to me and it worked fine on his car. after installing it and taking it for a drive i've only been able to reach 0.5 bar and after that the car begins to hesistate and sputter. it will reach a little more boost while sputtering but not much.

could have i messed up the install? the car was boosting perfect with my old actuator
