I did a search and found this thread, hoping to find a "secret" to getting more MPG out of my 01 Burb's 6.0. It is a 2500/4l80e with 4.11's and 17" hummer wheels with a 285/70/17 and I am darn lucky to get 10mpg, but I have a heavy right foot and cruize at @80 mph +/-. I put a Summit cold air kit (K&N kit for quite a bit less than the K&N kit in a K&N box!) Flowmaster cat back exhaust w/Edelbrock headers.

So those with tuners, did you see good enough gains to outweigh the cost of the tuner?? Looking at the Edge econ tuner??

I'd be happy with 15mpg??
