347 Stroker Engine Build TPS Adjustment
|
After installing the 75mm throttle body (PN SUM-227202; $171.95) and EGR plate (PN SUM-227502; $61.95), Johnson adjusted the TPS. The signal voltage (green wire) at closed throttle should be less than 1 volt. There is an adjustable mount built into the Summit Racing throttle bodies to make this adjustment easier.
