How much are these costing now? I just KNOW I'd be a perfect tester for one!

 

I am getting 1.4 (hand calculated) extra on highway, which is what most of my driving is. My True Flow XDI gave me about 2mpg extra. Half of the benefit of me getting this chip was to be able to upgrade it later. It makes it easer to get these purchases pass the secretary of finance (read: wife). I have not upgraded it yet, but with diesel at $5.19 here it should pay for itself very soon.

 

Man, that is a huge improvement for adding an intake system!! Was the TrueFlow added before or after the Quad? Thanks.

 

I just installed mine last night. I drove to work about 70 miles and noticed a pretty good increase in mileage just by looking at how little the fuel needle droped compared to the usual drop. Will post more when I fill up.

 

The true flow was added first, but to be completely honest it was done just after the 70k service interval. I probably got the extra mpg from other things as well.
