You only need 1 TP sensor.

You can run all 8 injectors using both injector outputs from MS, without any additional hardware. (4 injectors per bank)

Are these typical lo-z Holley injectors? If they are, you will need to use PWM to drive them. I am running 4 lo-z injectors on a 900 cfm Holley (ProJection) and they work very well.

Hope that helps.
