With the proper adjustments to things such as timing, shift points, etc., yes it will improve fuel economy at cruise.

Fuel mileage is based on laws of physics - air resistance, weight/inertia displacement..... but in reality, it's all just the optimising of the tire pressure, air filters, eliminate excess weight, alignment, y'know, all the things we have heard since 1973...

There may be a few things to do to, modify shift points, kill AC and other loads at lesser points, lean out the mixture, and even richen it for better MPG (GPM?) under load, but, may I ask, why would you care about MPG if you have a Hummer?????

My uncle just bought the H2, and he asked me if i could use EFI Live to get better gas mileage. He's getting 8 mpg.
Thanks for the info,
Steve
