Granatelli or Quadzilla
 

Both of these companies offer a mileage "tuner"
Granatelli advertises 50 HP & 150 TQ ( i think )
Quadzilla ...not sure
Anybody have any experiance with either one of these good , bad, or otherwise please let me know.
Would either one of these be good for a daily driver as well as being an ok low end power adder?

Thank You

my brother in law has had the quad mileage tuner on his truck for 1.5 years now. he loves it. went from 18 hw to 23 hw. he says the power gets the job done. he hauls 20+ thousand pound trailers through the texas hill country with no problem. if you have ever driven through it you will know how impressive it is to not feel boggish. id go quad. easy install if you can unplug stuff and plug stuff back in it is a easy install.

oh yeah... nice name and :hi:

I ran the Quad Max mileage for about a year and just recently upgraded it to the Xzilleraider2 XZT which is a 65hp and 165tq tune. It seems that my mileage might be slightly better with the XZT and definitely more power. I have only had this tune for about 2 1/2 weeks but I am very happy with it. I have had zero problems with. I dynoed my truck with just the intake and muffler deleted all stock other wise it put down 292hp and 519tq. After I put the Quad on there with the XZT tune downloaded on it I took it back to the same dyno and it put down 352hp and 690tq. The nice thing with the Max mileage if you want more power later all you have to do is just fill out a form on their web site and for a $120.00 you can download different tunes. Just my .02 sorry for rambling on. All in all my mileage has went up about 2 to 3 mpg.

so these are made for a stock truck application? by the sounds of it my tranny & wallet will be safe if i install one of these then?

Thanks for your help

The mileage max at least was designed with the stock truck in mind. A pyro and boost gauge are good things to have, but not absolutely necessary with just the mileage box.

I ran the M3 and saw better fuel mileage out of my XZT+ and X2 boxes.

and the two companies mentioned have the same product.
G says all quad does is make the boxes for them and they do the programing, but the product line up is basically the same.
