If it's tuned for 3.07 gears instead of 3.70 gears all your shift points and the converter lock up will be way off.
Your gas mileage is way low. My LS6/4L60E 98 Wrangler gets around 16-18 mpg and it has the aero of a brick.
If your car is stock I would go with a mail order tune. Check out the folks on LS1tech.com.
