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!
