Just go my tuner yesterday so stoked. I have a v10 it defiantly helped with power in the mid range, and my shifts are so much better, and solid. It used to be in such a hurry to shift into o/d it lugged. It also toned down the exhaust note, still sounds really good minus the gurgle it used to. This was the best investment I have made for it. Ill check mpg and update.

 

And that's in fuel economy mode?

 

i reset my mpg readout when i got installed the tune. showin the exact same now as it did before

 

those overhead readouts are as useful as a bag of nails and no hammer.

 

i think alot of mine was the cold winter to. its doin a little better now that its warmed up
