TPS TEC for 3.1, 3.4, all GM with round TPS Connector.

TPS voltage at Wide-Open Throttle (WOT) is a function of power enrichment (PE). If the voltage is below a certain point at WOT, the ECM will reduce the level of power enrichment and the engine will not perform to its potential. This device is completely transparent until 70% TPS, then it takes over and assures maximum TPS voltage for 100% Power Enrichment (PE) when you need it the most. The TPS TEC also corrects for low sensor voltage and "dead spots". Plug-and-Play, installs in minutes. LED indicators verify correct operation.
