So far at highway speeds 70-75 im runnin bout 700 trans bout 140 its kinda cold now like 20 degrees or less cant wait for the kojo tune and new turbo only a few more days
Congratulations. 140 sounds about right. Most of the 6.5s with an auto that I have had gauges on ran that or less, some ran as low as 120 on the highway.
I assume 700 is the egt. Sounds a bit high. Have you swapped out the downpipe and replaced the exhaust? The turbo and tune should help a bit.
