For the record, I have run various MarkD software versions in the past 3-4 years, and all of them consistently give better gas mileage. I switch back to stock very often to just for the shock value.

another great Mark D review
Just installed my chip/19# injectors and did a full tune up... Car runs better than it ever has, even the guy that tuned it for me said, "damn, this car has lots more power now, great upgrade" :-)
Mid throttle is much better now and the car is so much more responsive, amazed me, how much of a difference the small increase in REVS made...
Thanks Mark, you are the man.
