Why are the 01-02 Camaro High Octane and Low Octane Spark Tables so much more conservative than the 99-00? In the WOT cells the 01-02 tables are 9 degrees more retarded (19deg vs 28deg). Is there anything in the engine hardware that is substantially different that would prevent me from just utilizing the 99-00 Spark Tables?
Here is the HO Main Spark vs Cyl Airmass comparison table:
