I have a97 k1500 z71 5.7 and i get 13 city and 16 highway, and that is after doing dual exhaust, k&n intake, throttle body spacer, tornado fuel saver. I also have bigger wider tires which doesn't exacty help the mileage. I have had to replace the fuel pump, I now have 147,000 miles on it. Over all a awesome truck, highly reccomended

Cool guys, thanks, looks like I'm probably gonna keep the Blazer (my 94 5.7 TBI) unless i decide that I really need 4 doors among a few other things in a newer model. It seems to me I am getting the same milage out of my TBI as most are getting from a Vortec (I get 14, and am gonna work towards getting better)

Thanks for the replies
