I just stuck a superchipped ecu and what i have been told is a -31 actuator on my series 2 rst.It is boosting to 22-25 psi and then the engine is shutting down with a couple of bangs (sounds like a shotgun goin off).I have lengthened the actuator rod 3 turns and its still doin it.it even boosts when you lift off the throttle.I just passed a field full of horses and when i got the double bang they freaked and started a stampede.Why so much boost and what can i do to reduce it even more fellas?thanks.
