I recently purchased a Quadzilla Xzillaraider for my '04.5 Cummins looking for better mileage.

Well I just returned from the deer lease and when I pulled into the driveway and looked up at the trip odometer and saw 460miles I had a huge grin on my face! (And the needle is sittin on 1/4 tank)

I have NEVER got more than 350 miles to a tank... NEVER

On this trip my overhead console was showing 18-20mpg doing 65mph! I also have NEVER gotten more than 15mpg doing 55mpg at 1,500rpm empty highway!

After I filled up I showed have gotten a little more than 18MPG!

THANK YOU QUADZILLA!!

And I will ALSO say I now know why everyone is putting in the Tank Vent mod.... When I filled up my truck it clicked off at 26gallons. I sat there for an extra 10-15min and wound up getting 30 gallons in it... That will most defiently be the next modification on my list!

 

Unfortunately when I went to their website I no longer saw the Race box option.

Maybe Quad is coming up with a Crazy Larry style as promised??????

When you do Quad I'll be the first in line

I love my Race box and won't trade!!!

Well if you like the quad zxt, then you will love the race box. I actually get better mpg with the 100hp setting all around, and best hwy mpg with quad race box on lvl 2 stacked with the bddl on tow. I was getting 20-22 w/ the quad on lvl 2 on hwy, now with bddl stacked I see about 24-27mpg on the hwy going 65-70mph!! And I thought it'd be worse that way!!

 

do they have a website?

 

www.quadzillapower.com. They try not to sell to the public, they just want to sell to dealers and let them sell to you. Thats were me and the dealers on this web site come in.

 

So Daullydog let me ask you a question - I need to improve my MPG when towing and a little extra power would be good too. I have a MBRP muffler and drilled air box but thats it. What do you recommend and I really don't want to have to take a loan out to buy it (the wife will not cosign for it if you know what I mean).

Any suggestions would be appreciated.

 

I usually vote for the XZT on cases where you want more mileage with some power. Getting an adjustable you might get more mileage out of it but it takes longer to find the best setting for your driving and the truck's personality.
