I'm sure he could. Or just get the tuner and do it yourself.

I get 10 if I am lucky, difficult on a daily driver but as some others said, I did not switch for gas mileage. It would be nice to get 14-15 though. Hopefully, Dave W can give me some tips tomorrow after our dyno session. On my street tuning sessions the last couple of weeks I might be getting 5 mpg, Ha! I killed 18 gallons in 92 miles!

Eric,

That doesn't sound right as even when I drive my car HARD I still get at least 13.

E85 has about 1/3 the BTU value of gasoline. I am getting about 8 to 9 mpg at the track so the 6 mpg at the track sounds like it is in the ball park. The major advantage in running at the track is that it burns significanlty cooler then gasoline.

LMAO!!!

That is funny! I was seriously watching the San Francisco news when the guy pulled his prank on the TelePrompTer. I could not stop laughing.

I just switched over to 160# injectors. Let's see if it changes any. I don't think so, but maybe. I have a lead foot! Almost everyday I frequently hit low to mid triple digits I have two extremely long 1-1.5 mile long ramps to the freeway. Test it out coming and going to work. This eats tons of fuel. At WOT I burn 1.65 gallons/min.

1.65 gallons/min would be at 100% DC rather than WOT?

Oops, yes you are absolutely correct! Typing on the fly from memory. So 65% of that is about 1.1 gallons/min.

Thanks Shawn

Out making some longer data logs. Hit the boost limiter for the first time. Almost soiled my pants! 11.5 on second gear pulls is not perfectly corresponding to 3&4th gear pulls. Still need to trim a little fuel running slightly rich about 11.2-11.3. Decreasing very very slightly each run.

E85 was only $2.19 at my last fillup, so I'm not too worried about mileage right now. I'm going to enjoy it!

Just filled up Dave, down to $2.15 tonight! I would post picture but this App is totally hosed up. It won't post pics from my IPhone anymore. Some sort of parse error. Says to contact Shawn which I have and he says it is a known issue but not fixed yet.
