based on the approx number of results (~80) i think the voters for alero were me and oldsman, with spy being the GA.
Fear not though. the TCM may be different for the autos but for us manual guys there can' be much difference. The real test is if the tables are the same and loaded into the same area of the PCM, mainly the later, if they are we're golden. I can't image there would be drastic changes between our PCM and the J-bodies, other than the tranny.
I'll try and pull a bin dump from my PCM and compare it to some cav/sunfire bins i've got.
