What kind of MPGs are you getting?

[My01yuk]

02 tahoe 5.3L 12.5mpg i drive all city and drive hard also running 33s

Are you doing the manual calculation or do you have a DIC? That's pretty good with 33's.

Just finally made my 4" pvc intake and a new 18" magnaflow muffler..6.0 swap, long tubes, no cats. BB tune, 24s withi 3.73 gears and I got 19.7 on my last trip home from school. 170 miles and 8.6 gallons i think it was. I have made the trip probably 50 times, and ive never been above 17.9..i was set at 72 the whole way..

Only had her for about 700 miles so far but I'm averaging 14.75 city/suburban driving and that is with a stock 02 Tahoe LT with 5.3L, 74,000 miles. Going to change the plugs this weekend and see if it helps any. I know they are good for 100K but I'm going to change them anyway.
