u7130 diagnostics? Poor fuel economy?

Mike, I meant no disrespect. And yes timing and such will improve mileage. But there is no way when I'm running around on extreme that I'm getting better mileage. Tow, I'm sure it's better. Extreme, not gonna happen...

And I don't expect anything but kick ass tunes from you and excellent service as always.

That is why I have been running on tow and performance, and driving like theres a egg under the pedal (for the most part). I have only ran it hard for comparison on the tunes.(The fuel economy was figured on a long trip with cruise set. No hard running)

If you look at an older muscle car used tons of fuel to make horsepower and about 6 MPG average. Newer performance vehicles run high horsepower with good fuel economy. Look at the new GTO versus the old. Old was about 400 HP stock with about 8 MPG average. New GTO is 400 HP stock with 26 MPG average.

Just wanted to update you, I did install the tunes you sent, and updated the tool to the latest version. The tunes do seem to have considerably more power, and I just got back from a short trip and milage is up by about 3.5 mpg. Now I am up to about 24 depending on how hard I drive. Thanks for all the help, and what a great product! I also found the logging and trip functions after the last update, they are great!
Thanks again.
