Any of you run this module? Do the down loads work? Have a 2001 Cummins,auto trans. Was considering purchasing one.
Thanks.

I have a pulse on my 01. It's been on there for less then a week and I love it. I guess there is 26 different tunes you can download free which I have not done yet. The guy that installed it, installed a pretty BA tune so I will leave it at that for now. Your auto is not going to live long if it's stock.
