I tried the "a" version and it did well. Got about 1 MPG better when driving in the city. I went ahead and upleveled to the "c" version and have a short trip planned this weekend.

I downloaded the crom and flashed my 2010 Challenger R/T (6-speed) with the 93-Oct CAI Tune. Have not yet road tested but will let you know after some testing.
