Interested in the last part regarding the 7AT on otherwise stock car G37

Since this got bumped, I should add that my mileage results are pretty much ~2 mpg better than the stock tune. I'm getting ~400 miles per tank when I drive it easy and 300+ with an average amount of fun. I used to struggle to get 325 on a tank (I consistently fill up between 17-18 gallons every tank). I got nearly 250 miles on the tank of gas I took to the track (though it was only 6 laps at COTA).

75 extra miles should be a little over 3 mpg, so with some statistical variations I'm seeing 50+ miles per tank more than prior tune. I have to say this was unexpected, so I'm pretty pleased. The data I have was logged over the last 10 tanks (~4K miles).

Btw, I've got some vacation scheduled this month, and I'm hoping for dyno time in the following weeks after I return :tup:

Any updates bout the tune?...I'm coming back from deployment in a few months and I'm really interested in tuning my car ...I'm bout 1hour from Austin ...so I would like to know more bout this ...and joe let me know if you down to tune my car when I get back!!

The only update I have right now is I am very happy with the tune. Work has picked up pretty good, lately, and I haven't had a whole lot of free time.

Just give Joe a call or PM him here on the forum. I'm sure he can help you out. If you have difficulty coordinating a time, he offers an e-tune where you get a cable, drive the car around and data log for him, then send him the data, and he sends you a tune. He gives you the option to purchase or borrow the cable (2 wks at a time).

Ok ...il pm him ...I would definitely like to see a dyne sheet when ever you get it dyno
