i kicked my throttle tonight and achieved around 7psi with -14 ign timing. I can go to -20. this with a 30 percent throttle opening that reads 16 at idle, so im only adding 14%.

My goal is to get the SAS system to function and provide extra boost to a throttle kicked set up. This does two things..

SAS keeps shaft speed up, and to counter surge from the back pressure on the intake side, I will bleed some of it through the motor.

Im part way there. So far using parts that are pretty close in function to OEM, and using only a couple extra resistors and speaker wire for my map transitions.
