Has anyone tried this module? Dose it really increase mileage 8-12%
I'm wanting something to increase mileage and was wondering if this
was a good choice. Thanks

 

Any input? Surly someones tried it.

 

I recently purchased the XZT+. I took a short trip on the interstate running it in fuel economy mode. I went from 20.4 mpg on summer fuel to 21.3 mpg on winter fuel. I hope to gain a little more when I can run it with summer fuel. With my gears I don't think I can do much better.
With your gears you should do better.

 

i had the banks big hoss and got 21 mpg tried the edge comp on ez mode and got 18 the only thing diff was really windy when a tried the edge
u could try a cold air intake might help

 

My brother runs the max mileage and see's about 2mpg gain (99 with air intake bone stock other than that)

 

Thanks guys. I think I might try one sometime. I'll post the results. Totally stock my truck made 19.2mpg.wih airdog 100 i got 19.8mpg hand calculated. My test route is 54.9 miles, Cruise set on 70mph, power service,
and tank filled up to the neck were you can see the fuel.

 

My mileage went up 3 mpg with 40-60 injectors. This may be something you want to look at also. I've read on the sites that you can usually get a gain if you keep them under a 100hp. Also the XZT+ is nice if you want a little extra power at times. Like you I always hand calc and fill up till I see the fuel in the neck. This site has pretty good prices on modules.

 

Dave2001 Which brand of injectors did you use?

 

I have the Bosch 275 RV 40 HP injectors. They were purchased from PDR Diesel Performance. The web site says they add up to an additional 40HP and are great for towing and mild performance while gaining up to 1.5 mpg improvement in fuel economy. Some people say they add 60hp on a HO engine. Not sure about that. With just the injectors the truck (90000 mi) had a lot more get up and go. At first they seemed to smoke a little under acceleration but that cleared up after a few hundred miles.
