Well put in the new sensors and still had noisy TPS signal but had more range in the throttle once I calibrated the AEM to compensate. Also took out the angel eye wiring that was running along side the HPF AEM harness. That seemed to clean up the signal a bit. Also secured the main ground for the AEM better with copper washer as the HPF catch can mounts to the main Ground terminal for support and seemed it might not be flush.

Spent a lot of time setting up the AEM fuel map, warmup calibration and signal Filter so it was not triggering the accel pump inadvertently. Now I have really stable AFR from idle middle and top end. Runs fantastic. This is the kind of stuff I love digging into the inner workings of the AEM.

I'm a perfectionist when it comes to how a performance car runs and so ill be tweaking it further.
