Hey guys I looking for some help. I have found a 2001 Tahoe, 5.3 4wd whippled, other than that stock (does have 18's). Does any body have a or know someone with a similar set up? I am curious as to what the mpg will be. Should I expect 16 city and 19/20 highway? Oh yeah this will be for my wife, so that may have a drastic effect on fuel economy

With mi FI 5.3l Tahoe I'm getting 17 mpg hwy and 13~15 city. Do you know the axle ratio, if it has a stall? When my truck was all stock I got 16mpg hwy. and after Headers,cam, E-fans and tune I went up to 18mpg.hwy.. Radix install dropped me to 17hwy but is still higher than when truck was all stock.

Ok thanks. I dont know the axle ratio, but I figured what you posted would be right where this thing is at.
