For the longest time I put off doing the tuner. I was having tranny issues and didn't want to chance loosing my warranty. But with the exhaust alone not really I avg. 12-13 on mixed driving and 15-16 freeway @2100 70mph. After I put the tuner in about 3 yrs ago each avg. rose 3 mpg but the power differance with the tuner is AWSOME and im sure the Exhaust gains are much better with the tuner installed. So YES I saw an increase in milage.
