The tune feels great otherwise, but it would be perfect without the boost spikes. I am currently attributing my timing pulls to the last 2 injectors that were not replaced with the recall. Those two cylinders are usually more noisy than the others.
when you press the button once, you will still get intervention, just less than if the system was fully on. I got throttle closure in 3rd gear once at 60 mph and thought it couldn't be traction control but it was.

Spark plugs solved my timing drop issues. Since you think the injectors are the most likely cause, I guess you should start there. Good luck
