Default Fuel economy

I drove my car on a 650 mile roundtrip yesterday and on one of the stints I had an average speed of 67 mph and did that on 22 mpg. That is better than my daily driver at that speed!

The engine is stock except better breathing in the form of lowrestriction airfilter and headers.

LSx power rocks.

We have seen 27mpg average over 1000 miles. The Gen III is an incredible package!

If you can get ahold of a GTO computer, you can enable lean cruise and pick up a good 3mpg more than without it.
