wouldn't be the first time a new auto part failed.
Somebody has to do it.
The new Delco sensors aren't as reliable and good IMO as the OEM ones that came out on the car. That one from Amazon is the newer design. Sneak into a JY and get you one of the old "Fin" style sensors.....Trust me, they work way better.

Looks to me like it's just commanding way too much timing. Do you still have the stock pcm?
