Hey guys i have a 2003 cummins and i want to order a chip or programmer for it but am not sure what to order. so i would like some opinions. my truck is a 2003 5.9 turbo auto tranny:/ with 97,000 miles i have a 4 in mbrp and a airraid filter. i was looking at the smarty jr and the diablo sport predator. Thanks guys.

 

Smarty Jr or Smarty would be your best choice.

x3 on the smarty

 

Thanks guys, the smarty jr is what I will order, what setting should I run it on to be safe with the stock auto tranny?
