39 Bolt On Dyno Test The Main Event

Three-Valve throttle-body swapping requires installing the OEM throttle-activation motor and TPS on the BBK piece. As a drive-by-wire unit, throttle-position voltage must be verified before removing the stocker (Tony's is 1.20), and then duplicated (within 1.19-1.31) when the upgrade is in place. The PCM will kick into Fail Safe mode if TPS voltage falls outside the recommended parameters. View Related Article
