I was thinking about posting this exact same post, just got my car tuned w/ stg IIe and for the last half tank my computer is reading about 17.5 mpg vs my usual 21mpg on 91. But it looks like my computer is reading low as my acutal mpg is about 18.5 based on miles driven vs gallons pumped. I've only driven about 200 miles since being tuned on e85. What I will say is that my car feels like its driving smoother when under boost which helps explain my less mpg, lots of fun I will tell you that
Standard stg 2 stuff
perrin panel filter
08 Spec B UP
3 port
walbor fp, stock injectors
Torqued Performance road tune, mile high
My e85 tune gained approx 23hp/28tq over 91 FYI
