Goes against the grain for some... but I'd like to hear some people's experiences with their tuners and any improvement in fuel economy rather than any outright power gains.

I am pretty satisfied with the power output of my truck (well, a leeeetle more wouldn't hurt /ubbthreads/images/graemlins/grin.gif), but if I was to purchase a tuner, I'd be looking more for an improvement in fuel economy.

So for those willing to share, what (approx) gains (or losses) have you seen in fuel economy?

 

[rwilliams]

I put a programer on (Super chip) I tried it in all modes and found that it got the best mileage in stock mode.
I also have a cold air induction and exhaust mod.

 

[spdiesel]

Heres an option to consider

I use the built in HPOP gauge on our in house test vehicle when on the highway to maximize the mileage. Our test vehicle gets at least 17 on the highway and we aren't easy on it by any stretch.

you can stack this with other tuners on the market that plug into the OBD.

I have hog performance exhaust a volant cold air intake and the quadzilla race programmer and on the Highway I see between 22 and 25 MPG going 80

If you just want mileage then this is by far the most economical solution:

There are many products that can and will improve mileage, but the XZT is the only truly "Economical" solution if you are wanting a little extra power and fuel mileage.

I assume you are using the overhead computer for these numbers? 25MPG at 80? I cannot get that out of my Jeep Liberty CRD at that speed. The only true calculation is hand calculated. At that speed I would think 16-17 is more at the top end of what is possible without violating some physics laws.

QuadBoenker,

I'm assuming the XZT leaves no trace on the ECM as well and is a safe alternative for mileage and power.

How many stages (settings)are on the XZT going up to 65hp?

 

[Machine]

I just started running Quad's XZT on my 2006, and after one tank of diesel the city mpg has gone up 1 mpg. On my current tank of diesel, which consists mostly of empty highway driving, I'm at 250 miles with a little less than 2/3 of a tank left. I'd say that it's a drastic improvement.

The XZT is one setting at 65HP, and the install is easy - it would be easier though if you have small hands.

The only thing that sucks is that I can't get my truck to blow smoke. I miss that from my stacked DMAX, but knowing that Power Strokes are prone to puking, I'll just have to live with this conservative increase in power.

 

[QuadBoenker]

The XZT is not adjustable unless you have the Commander to go with it. With the Commander you have 2 more levels (25 & 45) plus stock.

The XZT won't leave any traces either.

We can make them smoke, but with the VGT's it caused a few surging issues. The actuators on some trucks are finicky when it comes to soot. If we were in the custom tuning business it would be easy to adjust, but with distribution we want 100% trouble free products so no smoke = no problems.

Now don't let the no smoke fool you, they run pretty darn strong and in some cases the might be slighty underated. There was one at the 6L shootout that was pretty impressive.

Quad,

Would you say I could also use the Xzillaraider Adj Module 0-30-60-110HP setting it at the 60hp stage and get similar results as the XZT? The reason I ask is because I like the economy piece since I tend to drive conservatively but would enjoy having a little more get up and go if I get a wild hair. I realize the Adj. Module costs more as well....

 

[bogeyman]

Quad,

Are there any issues or concerns with the Xzillaraider and towing? Does installation effect the vehicle's towing limits in any way?

Please explain yourself. that's a pretty bold statement to make.

You would see similar results, but the XZT program is slightly different and makes the torque slightly quicker than the Standard module on the 60 hp setting. This is mainly because the XZT was for the guys towing. If you are empty you will not notice the difference hardly at all because you run through the low end so fast.

There are some people that claim they get better mileage in the 30hp setting and others that swear the 100hp setting gets the best mileage. In some instances the different driving habits affect the mileage on the various settings.

If you use the XZT then there are no concerns or limits. IF you want to use the 120hp or higher settings then you need a pyro, but you will find that the temps are very low for the power.

 

[ERyser]

Thanks for the update Quad.

It is pretty simple.

To start with it is the most economically priced part for the 6L that is available. Not only is the most economically priced it is the only one in that price range that modifies the timing. You can get mileage without modifying the timing, but advancing the timing is the way to get better mileage.

 

[spdiesel]

This is one of those brand specific claims you are making. And yes yours is 'cheaper' that is very true. With the built in display and compliance products on the board I am unable to price ours as low as yours.

 

[QuadBoenker]

It has also proven itself in the real world and on the dyno by a third party. It has been put through its paces by other members here for the sole purpose of writing a report on it.

Now you make a big fuss about your display. 05-06 trucks already have a boost gauge so it is redundant. So that leaves you with an Hpop display that displys the data in 100 incrememnts at best. I think the HPOP display is cool, but not needed in such a low power application.

 

[spdiesel]

As for the display...DING DING..the best selling product thus far is the Stage I with the HPOP gauge. You can come on here and suggest what you want. Boost gauge redundant maybe. But 6.0s are not the only platform this serves. Neither does your board. It's also why we spent that extra R&D time on compliance so when someone has a CB or inverter the board doesnt' continually reset. or when you try and run it with a TST.
