Is there a performance chip available for the 8.1-liter Chevy Vortec engine? Do they work /help? I'm interested in better performance as well as increased gas mileage.

I'm currently getting around 7.5 mpg and performance is ok, but I'm not towing a toad, yet. I figure mileage will go down by a couple mpg when I do. What kind of cost am I looking at for a chip if they're available?

The E.C.M. (computer) is programable on that model. I use a DiabloSport Predator Tuner. My M.H.P. increased and so did my power. You can flash your E.C.M. with a program that is all ready written from Diablo or make your own.
I really like this tuner.
