Ways to give my Duramax 6.6L more torque.
I want to give my truck even more torque. Please Help!!!!
Get a different torque converter for it. JCWhitney.com.
I'm pretty sure that they sell chips that you can put in for that. I know they do for more horsepower because my brother has a duramax and talks about how he wants to get a chip for more horsepower.
