I have a ly6 6.0 and a 4l80e run by a '10 e67 and t42 "colorado base tune", Im pretty sure that I read that they came out with a fix for the convertor remaining locked even at 0%tps which is what I would like but I think it was only for the older pcms without a t42 tcm. Things might have changed since Ive been out of the tuning loop since last winter but looking over my editor files I cant find the apply/release per tps tables. Just apply/release per vss. Thanks and I do run the newest version of hpt as of last winter.
