How much extra power do you want?
Mainly just mileage but I would say between 50-100
Do a search for the Mcrat 20/20 tune(google) and timing calculator how to in this section, should accomplish what you are after.
is it easy to do, i am very unfimiliar with hp tuners. also do i need a bigger exhaust truck is still all stock
Its not to bad. Read the instructions, if you have any questions ask.
Probably should check out a Duramax forum before you get too far along there.Quote:
