anyone on here gotten a tune for a the I4 6spd? Kinda curious as to how much it affects the performance.
i was looking at the WAMS tune for the 2.4L but since I have a 6spd auto it said i needed to bring it in or something for the TCM. Someone please make some sense out of this for me.
is the tcm bit actually necessary?
