To tune or not

Zay370z

Does an uprev tune improve MPG at all?

I would definitely say yes; as it will put your Air/Fuel ratios in check...as you are more than likely running rich.
Before adding my heavier wheels/Tires...avg was 24/25 & 28/29cruising 70-75 on a trip.

I was told that a 1-2 MPG increase is likely although, I am not getting the tune done for that reason. When I drove home from ZdayZ in 2015, I was averaging 30 MPG when I pulled into my driveway (all freeway).

Unsure what your bolt-on's are...as I can go 500+ miles on a tank of fuel @cruising speed of 70-75mph.
28,29mpg on Hwy.
24,25mpg spirited driving; all after tune w/CAI,free flowing exhaust w/test pipes.
Ensure that your tire diameter is oem/as a shorter tire will mislead your mpg.
#1 reason for my tune (ensure proper air fuel ratio@wot)
#2 maximize hp/tq from money spent on bolt-on's
#3 felt like I gave it a small shot of nos after tune...as you can see that most people gain 20whp (+ or - a tad) no fuel mileage hurt on my end.
#4 no speed-limiter anymore,,,so no need for explanation here.
#5 knowing my engine is healthier & not leaning or over fueling.
Money well spent!
