Is anybody using it? I'm looking to get better milage and a little more power w/o messing up my truck....and knowing me, if i would get one of the more powerful modules i'd leave it on the highest setting and tear up my tranny.
Inputs about power/mpg gain on the 65HP XZILLA XZT and alternatives aprecciated.

 

Ive got one on my 2006 with 48RE. I havent noticed mpg change either way, but I already get 20mpg@75mph and I read on another thread that mpg gains are seen mostly by people getting bad mpg to start with.

It is a nice power addition. When I put it on I got used to it quickly and thought it wasnt that much faster. But then you turn it off, and the truck feels alot slower.

I dont know what to think about the rail pressure increase though. It seems to raise the pressure a little at all times other than idle. This is an interesting read: http://www.drperformance.com/TDR48.pdf

I have the Commander gauge, it is a great product. I added the rail pressure sensor, it is interesting to see.

 

Good module, I've been running mine for about a year now, no problems, money well spent IMO.

 

I have this box, with it plugged in the overhead reads much more optimistic than hand calculated. I love the modest HP increases. I haven't unplugged it in awhile though.
I have been happy with no known issues to this date. I can really climb hills while towing.

I have had mine for over 2 years now and love it. I did not want a adjustable box because of towing the 5th wheel so much and being afraid of blowing up the tranny. I did notice a 2 mpg gain both empty and towing when I installed it on my truck.

 

Can you win a race against your wifes hemi? with the tow box?

Good info, thx all.

 

The xzt works well for me. It really made my SO come to life, but it also makes my throttle act a little weird.

 

"Can you win a race against your wifes hemi? with the tow box?"

Right now yes. We are waiting on the new Bully Dog programmer to come out for her Hemi and once that is installed I may not be able to.

 

i guess i've had mine in for about 1.5 years and love it. it really woke my truck up and gave it better mpg....probably around 1 or 2 mpg. i haven't had any problems either.

 

That's good to hear, i was hoping you'd say that.

Now about your wife having a faster truck then yours soon......you gotta do something about that; what are the plans?

 

Other than a PML deep transmission pan for my truck that is it. I use my to much for towing and a daily driver so no more mod plans for mine. The only reason we are going to get a programmer for hers is to try and get better mileage out of it. 14 mpg on the highway, well that ain't to good.

 

Had mine on for about a week now. It really woke it up and I don't think I will need to worry about my tranny. Have not run enough fuel through it to give you an answer, but when it hits 1850 or so rpm it pulls really good.

Next investment............Torque Converter.

 

I feel you; Before buying my cummins the dealer gave me a 2005 Ram 4x4 with hemi to drive over the weekend...drove it softly for 150 miles, topped the tank off and needed 15 gallons to do so...10mpg sucks.
