i just did some updates on my tuner on my 6.4 and i decided to change the tranny tunning as i didnt like how it locked up the tc in 4th and 5th so soon. it seems to rob lots of power by dropping lots of rpm when hitting the highway when in locks in 4th and 5th so soon. i do like the 1-2-3-4tc-5tc better then the 1-2-3-4-5tc for pulling tho. so i went with the s1h tune instead of the s1m. it now grabs 4th and 5th lock much later keeping the rpms up.
just wondering if any body has tried both settings with pulling trailers thru the mountians and which one you like better?
i also didnt like how long it held 5th for up the hills when following slow traffic creating higher egts. so my thoughts are that s1h will grab 4th sooner creating more rpm and less egts...
