Oh didnt know you still had the stock throttlebody give it a try its a very simple swap, wont loose anything.
Ps. You can see how actual TPS drops while desired was at 100% in the first spike on the latest printscreen. Second time it didnt fall on its face but seemed like it took more time than it should have to match the desired you can see the actual sloping upwards.
Try the stock throttle
