I lifted slightly after the power came on.The TPS Sensor is moving around too. Did you lift? If not it may be loose.
It does look like you are breaking up or you have a miss.
The intake manifold is an edelbrock super victor, ported by TEA. Is there something specific you are asking about? The main power for both MSD (7530 box) and the FAST (classic sequential individual cylinder control box) are connected to the battery.What does your intake look like? Also is the main power for both the Fast and the MSD directly on the battery?
