DD Tune I see 14-15 city and 21highway doing 65.
Before top end build with PPE on tune 3, 24MPG was the best I saw. was 100*, did 60 on the dot and round trip of 1000 miles and average 24.1MPG.

Big tune: 12 city 17 highway but I'm also beating on it pretty hard doing rolling burnouts which are NOT over rated as some think.

Normal (70% city/30% highway) = ~15-15.5mpg

Highway. Just did my first straight hw run today filling up before and after, got 17.6mpg with 8.5 gallons.

Both those numbers are hand calculated and much much better than I had expected!
