a family member has an 06 chevy duramax and mostly pulls a 4 horse trailer with a 12 ft livin quarters and he was wantin a chip to improve mostly fuel milege but of course everything else i was wonderin what would be the best chip for him thanks guys

 

What is his budget?

 

n/a

 

a lot is goign to depend on budget. and if he already has guages for the essentials. Does he want on the fly adjustments or would something like the superchips work for him?

 

I would say a superchip. it helped my dads chevy.

 

Alright it has been long enough. If he wants more power he can trade it for a dodge.

 

The PPE is a good programmer for Chevy's.

6.0 or7.3 < 6.6 < 5.9 or 6.7

 

lol, knew someone was going to have it covered sooner or later!

 

If he wants real power then PPE or EFI Live is the way to go.
