I'm interested to see how the modification to the cam position sensor plays out. With the stupid aem ems,I had to reduce the air gap between the sensor and pickup points for cam and crank sensors. Factory subi ecu's have higher tolerances to changes in the hall sensor readings and will still sync (to an extent) with variances in air gap. I'm not sure if due to the slight difference in position of the sensor and difference in pickup points if you'll encounter issues with getting a solid reading by the ecu. Most likely you will be fine but if there is any issue you might have to look into finding out the specs for the sensor gap and getting it to that with a feeler gauge.
