Greetings team, below is a log of my 2009 cobalt ss/tc. The car is registering at 50% tps at all times. Whether at a dead stop or in a WOT pull. Attached is my log any insight or similar issues? 4.hpl

Any codes? You either had a fault reading the TPS or you potentially have a bad throttle body. ECU reads voltage and not actual physical throttle position, so it's possible your throttle works but the TPS is passing back the wrong signals.
No codes at all. What would you recommend ?
post the tune.
The most hated, make the most power.

Tune attached
Other than one Optimum Spark table, your tune matches the other GMPP Cobalt Tunes I have.
Your log definitely shows a lack of throttle position variation. I'd be looking at mechincal/electrical causes. **Is the mic on?!**
