so the wife drives a 2000 tahoe z71 with a 5.7. it has k&n intake, 3" flowmaster cat back. we have owned it about 4 months now. first checked mpg, was getting 10.4 city all stock. now with mods getting 9.3 mpg. this is with my wife driving. I would think it would be better than that. we really love every thing about it but the mileage. I know its no econo box, but my 97 5.7 2wd silverado gets 16-17mpg in town and thats with me driving ;-) any ideas? it also only has about 3k on complete tune up. I also wouldn't be apposed to ditching all the 4wd parts to save gas if it would be enough of a difference. 2wd's are hard to come by around here. Thanks
