I'll be doing the tuning. Depends on how much time we have or what you want on the car, we can get it dialed in good enough for mostly stock car. I just tuned a regal that we Intercooled and he said he noticed an increase in gas mileage, that was with a 3.2" pulley and 2-3 degrees of added timing on a 12.1 A/F ratio, for a non-IC car you want it to run a little richer 11.5~. Most of the time we are tuning to make power and do not look into mpg, it's just a bonus if we gain mpg. There are some spots in the cruising timing that we can raise to gain mpg on the highway, but I have not looked into that much. I'm sure I can figure it out by then if your looking for more mpg and a lil more power tune.
