i have heard that bully dog is pretty awsome for the duramax. but it depends on what you want: Max power all the time, or max power that can be used while towing.

even though i dont really like my hypertech for my gas motor, the ones for the diesels seem to be quite a bit better. plus you can tow on stage three.

unfortunatley my uncle sold his 03 duramax before we had a chance to put a programmer on it. let us know what you get and how good it is.

good luck

 

thanks man and yea i deffinetly will let you guys know how i like the triple dog if i wind up gettin it.

 

check into the edge chips, ive seen some dyno results that show that they put out a little more than the others, plus you can program them to cut out at certain temps and when the tranny starts to slip

 

If you're talking Diesel....I have no idea.
If your truck is petrol....no chips....dynotune!

 

edge is a manufaterer?

I have an Edge programmer on my 02 Duramax. It makes alot of difference.
If you want to learn everything there is to know about Duramax diesels, go to Dieselplace.com. You can read about programmers and add ons until your eyes fall out.

 

i have a hypertech on my gas engine and its ok. i have heard a lot of good about bully for diesels, there was an episode on pinks with a dodge and it was a bad *** truck. from what i remember all they do is diesel i also saw them on horsepower and the guys were pretty impressed.
