Hi all,
I don't know if it's possible, but wanted to ask - Is there a way to make it so DEFCO doesn't unlock the converter everytime? Trying to squeeze all the fuel economy I can out of this 6.0 9-7X (was a 5.3), swapped in 3.42's, a little taller tire, and with summer fuel getting about 18 mpg (happy with that).
Thank you

Bonus question: can the TCC lockup temp be modified?
Thanks much
