Does anyone run a quadzilla xzt chip? What kind of milage increases did you see if any? Do you recommend this product? Thanks

 

The only thing I can say immediately is that before hand my overhead console said I was getting 12mpg. It now says I'm getting 14mpg and that is after taking everyone I know and their dog for a ride.

I'd have to get back to you on the mileage gains. But I will say I notice that it hasn't HURT my mileage like the Edge EZ I had. That thing did nothing BUT hurt my mileage.

 

I've only had mine for a few weeks. So far I would say there is no noticable increase in mileage.. but there is no decrease either. So getting more power without using more fuel.. it's like MAGIC

If you were to drive like a granny, you might notice the better mileage, but I'm thinking the times you drive like a granny and get the good mileage are offset by the times you use the extra power on hand. So if it all comes out even, it's all good with me.

 

I personally would not buy a box with the premis that you gas milage will be bettter. even though they advertise that I would consider it a bonus not mandatory on every truck.

In my case the gas milage does not seem to be any worse and the power is way up so I am happy.
