i have a friend who has a stock 02 2500 HD added intercooler,k&n, 225000 and counting, replaced injectors gm, he wants to see 1 mil, daily driver, the heaviest thing he pulls is a dog trailer, 2000 lb or less ... nothing, he wants mpg,drives interstate and would love the power. where should i start? Air breather, exaust, programmers?

 

exhaust, programmer and gauges ....

several programmers now have gauges built into them now.

 

thanks, do most programmers do the same for mpg?

---AutoMerged DoublePost---

whats the most popular all in one unit? easy to use? bang for buck?

 

You will also find that PPE programmers are very popular. They do not come with gauges.

They have some of the best tuning out there for the duramax.

I have an extra one for sale if you are interested.

 

its not my truck its a friends , i will be talking to him about mods in a couple of days, what $ r we talkin

 

I can ship you my PPE standard for $400.

 

I will tell him, have you ever heard of JAWdropper TRIPLE-A Twin stage Performance Fuel Optimization module i seen on fleabay sounds kind of ridiculous ? 40 mpg?

 

I never heard of it, but it sounds like a joke!

 

thats what i thought, whats the most mpg out of any gen duramax that you have seen?

 

The best I think anyone has gotten is about 21-22 mpg.
