dont see why you posted this , its always been this way ..  5.6 5.7 doesnt matter

what 5.7 gives over the 5.6 is the ability to use the powerlogger and a laptop to direct enter the parameter values  without needing to use the accelerator pedal

If I read it correctly...he clearly states he made 3 changes for the 5.7 version.

definitely changed the alky so you could have the delay, or not...

yes he added a feature that would take out the timing delay that he introduced with the 5.6 ALKY chips to avoid kr on street cars that would not have the alky fully primed on a quick stab
on the 5.6 alky chips the delay is there and you cant change it,   on 5.7 alky chips whenever you change the 1/2 timing it removes the delay .
  well aware of this as its something we saw at track with the first 5.6 chip holding timing lower than programmed 1/2 timing up to around 35mph and were not thrilled with it at the track ... so eric made the change  in the 5.7
